    During recent years a continuous reduction of mortality from breast cancer has taken place in the Western countries. We wanted to verify whether the actual therapy for our own cases deviates from our recommendations, although the surgeon, radiotherapist and gynaecological oncologist are on the same premises. We sent out questionnaires to all newly diagnosed breast cancer patients in the last seven years regarding their adjuvant therapy. Comparing these answers to our own recommendation showed a very good compliance regarding chemotherapy and radiation therapy. Adjuvant endocrine therapy showed a very poor compliance with an adherence of 77%. Overall we can conclude that endocrine therapy causes many side-effects that seem to burden the patients. In combination with the duration of the therapy this causes a severe reduction in compliance and length of the therapy.

    Purpose: To evaluate the efficacy of adjuvant chemoradiation therapy (CRT) for pancreatic adenocarcinoma patients {>=}75 years of age. Methods: The study group of 655 patients underwent pancreaticoduodenectomy (PD) for pancreatic adenocarcinoma at the Johns Hopkins Hospital over a 12-year period (8/30/1993 to 2/28/2005). Demographic characteristics, comorbidities, intraoperative data, pathology data, and patient outcomes were collected and analyzed by adjuvant treatment status and age {>=}75 years. Cox proportional hazards analysis determined clinical predictors of mortality and morbidity. Results: We identified 166 of 655 (25.3%) patients were {>=}75 years of age and 489 of 655 patients (74.7%) were <75 years of age. Forty-nine patients in the elderly group (29.5%) received adjuvant CRT. For elderly patients, node-positive metastases (p = 0.008), poor/anaplastic differentiation (p = 0.012), and undergoing a total pancreatectomy (p = 0.010) predicted poor survival. The 2-year survival for elderly patients receiving adjuvant therapy was improved compared with surgery alone (49.0% vs. 31.6%, p = 0.013); however, 5-year survival was similar (11.7% vs. 19.8%, respectively, p = 0.310). After adjusting for major confounders, adjuvant therapy in elderly patients had a protective effect with respect to 2-year survival (relative risk [RR] 0.58, p = 0.044), but not 5-year survival (RR 0.80, p = 0.258). Among the nonelderly, CRT was significantly associated with 2-year survival (RR 0.60, p < 0.001) and 5-year survival (RR 0.69, p < 0.001), after adjusting for confounders. Conclusions: Adjuvant therapy after PD is significantly associated with increased 2-year but not 5-year survival in elderly patients. Additional studies are needed to select which elderly patients are likely to benefit from adjuvant CRT.

    Background The combination of electrochemotherapy with immuno-modulatory treatments has already been explored and proven effective. However, the role of interferon alpha (IFN-α) adjuvant therapy of melanoma patients and implication on electrochemotherapy effectiveness has not been explored yet. Therefore, the aim of the study was to retrospectively evaluate the effectiveness and safety of electrochemotherapy after the previous adjuvant treatment with IFN-α in melanoma patients. Patients and methods The study was a retrospective single-center observational analysis of the patients with advanced melanoma, treated with electrochemotherapy after previous IFN-α adjuvant therapy. Five patients, treated between January 2008 and December 2014, were included into the study, regardless of the time point of IFN-α adjuvant therapy. Results Electrochemotherapy of recurrent melanoma after the IFN-α adjuvant therapy proved to be a safe and effective treatment. Patients with one or two metastases responded completely. Among patients with multiple metastases, there was a variable response rate. In one patient all 23 metastases responded completely, in second patient more than 85% of all together 80 metastases responded completely and in third patient all 5 metastases had partial response. Taking into account all metastases from all patients together there was an 85% complete response rate. Conclusions The study showed that electrochemotherapy of recurrent melanoma after the IFN-α adjuvant therapy is a safe and effective treatment modality, which results in a high complete response rate, not only in single metastasis, but also in multiple metastases. The high complete response rate might be due to an IFN-α immune-editing effect, however, further studies with a larger number of patients are needed to support this presumption. PMID:27069446

    Context: Adrenocortical carcinoma is a rare malignant endocrine neoplasia. Studies regarding outcome and prognostic factors rely on fairly small studies. Here we summarize the experience with patients with a diagnosis of adrenocortical carcinoma from a large tertiary referral center. Objective: The objective of the study was to identify prognostic factors in patients with adrenocortical carcinoma and evaluate adjuvant treatment strategies. Design: Patient data were collected in a retrospective single-center study. Epidemiological, patient, and tumor characteristics were analyzed for prognostic factors regarding overall and recurrence-free survival in Cox regression models (multivariable and univariable). Results: Three hundred ninety-one adult patients with the diagnosis of adrenocortical carcinoma were identified. Median overall survival was 35.2 months. Cortisol production [hazard ratio (HR) 1.4, HR 1.5], tumor stage (HR stage 3 of 2.1 and 2.1, HR stage 4 of 4.8), and tumor grade (HR 2.4 and 2.0) were identified as negative prognostic factors (HR for death, HR for recurrence). Mitotane therapy increases recurrence-free survival, an effect that was significantly further improved by adjuvant radiation therapy but did not impact overall survival. Patients with open adrenalectomy had improved overall survival. Conclusions: This study increases the evidence for adverse risk factors (cortisol production, high tumor stage, and high tumor grade) and suggests the following therapy approach: adrenocortical carcinoma patients should be treated with open adrenalectomy. Adjuvant therapy, particularly mitotane therapy in conjunction with radiation, should be considered to delay tumor recurrence. PMID:24302750

    Objective Although radiation therapy (RT) and concurrent chemoradiotherapy (CCRT) are the global standards for adjuvant therapy treatment in cervical cancer, many Japanese institutions choose chemotherapy (CT) because of the low frequency of irreversible adverse events. In this study, we aimed to clarify the trends of adjuvant therapy for intermediate/high-risk cervical cancer after radical surgery in Japan. Methods A questionnaire survey was conducted by the Japanese Gynecologic Oncology Group to 186 authorized institutions active in the treatment of gynecologic cancer. Results Responses were obtained from 129 facilities. Adjuvant RT/CCRT and intensity-modulated RT were performed in 98 (76%) and 23 (18%) institutions, respectively. On the other hand, CT was chosen as an alternative in 93 institutions (72%). The most common regimen of CT, which was used in 66 institutions (51%), was a combination of cisplatin/carboplatin with paclitaxel. CT was considered an appropriate alternative option to RT/CCRT in patients with risk factors such as bulky tumors, lymph node metastasis, lymphovascular invasion, parametrial invasion, and stromal invasion. The risk of severe adverse events was considered to be lower for CT than for RT/CCRT in 109 institutions (84%). Conclusion This survey revealed a variety of policies regarding adjuvant therapy among institutions. A clinical study to assess the efficacy or non-inferiority of adjuvant CT is warranted.

    Patients with AJCC Stage IIB and III melanoma have a poor 5-year survival rate which has been the driving force behind attempts to find an effective adjuvant therapy for this stage of disease that would effectively reduce relapse and improve survival. Immunotherapy with bacillus Calmette-Guerin (BCG), Corynebacterium parvum, and levamisole have not been successful in achieving this goal, nor have trials with chemotherapy in the adjuvant setting, including high-dose chemotherapy with autologous bone marrow transplantation. The recent Eastern Cooperative Oncology Group (ECOG) 1684 study showed significant improvement in relapse-free and overall survival with high doses of alpha interferon (IFNalpha) given for 1 year. Lower dosages of IFNalpha have to date been unsuccessful in impacting upon long-term survival. Recent data with vaccines have been encouraging, and the GM2-KLH vaccine is the focus of ongoing intergroup study comparing this treatment with IFNalpha in resected Stage IIB and III melanoma. The various regimens are reviewed in this article. PMID:9588723

    Although protracted cognitive impairment has been reported to occur after radiotherapy even when such therapy is not directed to brain areas, the mechanism remains unclear. This study investigated whether breast cancer patients exposed to local radiotherapy showed lower cognitive function mediated by higher plasma interleukin (IL)-6 levels than those unexposed. We performed the Wechsler Memory Scale-Revised (WMS-R) and measured plasma IL-6 levels for 105 breast cancer surgical patients within 1 year after the initial therapy. The group differences in each of the indices of WMS-R were investigated between cancer patients exposed to adjuvant regional radiotherapy (n = 51) and those unexposed (n = 54) using analysis of covariance. We further investigated a mediation effect by plasma IL-6 levels on the relationship between radiotherapy and the indices of WMS-R using the bootstrapping method. The radiotherapy group showed significantly lower Immediate Verbal Memory Index and Delayed Recall Index (P = 0.001, P = 0.008, respectively). Radiotherapy exerted an indirect effect on the lower Delayed Recall Index of WMS-R through elevation of plasma IL-6 levels (bootstrap 95% confidence interval = −2.6626 to −0.0402). This study showed that breast cancer patients exposed to adjuvant regional radiotherapy in conservation therapy might have cognitive impairment even several months after their treatment. The relationship between the therapy and the cognitive impairment could be partially mediated by elevation of plasma IL-6 levels. PMID:24756915

    At any point in time, psoriasis affects 2-3% of the world's population and has one of the biggest impacts on quality of life of any dermatological disorder. Treatment is extremely costly and prevention of disease progression in severity and extent is crucial. Psoriasis treatment should include skin hydration (regular use of moisturizers and emollients), careful, gentle skin cleansing, and identification and avoidance of Koebner phenomenon triggers (excoriation, maceration) and infectious foci (Streptococcus pyogenes). Moisturizers have been shown to significantly improve skin conditions and quality of life for psoriasis patients. They are a valuable first-line treatment, as dry skin is common and adds to the irritability of the diseased skin. Most patients respond well to topical treatment with topical corticosteroids, emollients, coal tar, anthralin (dithranol) or calcipotriol. Emollients are the most prescribed products, providing transient relief from irritation and some possessing anti-inflammatory properties. Moisturizers and emollients should be used in the following cases: minimal psoriasis, napkin psoriasis, psoriasis of the folds, psoriatic skin damaged by previous local treatments, and in pregnancy or women of childbearing age.

    The practice of yoga regulates body physiology through control of posture, breathing, and meditation. Effects of yoga on autonomic functions of patients with refractory epilepsy, as quantified by standardized autonomic function tests (AFTs), were determined. The yoga group (n=18) received supervised training in yoga, and the exercise group (n=16) practiced simple routine exercises. AFTs were repeated after 10 weeks of daily sessions. Data were compared with those of healthy volunteers (n=142). The yoga group showed significant improvement in parasympathetic parameters and a decrease in seizure frequency scores. There was no improvement in blood pressure parameters in either group. Two patients in the yoga group achieved normal autonomic functions at the end of 10 weeks of therapy, whereas there were no changes in the exercise group. The data suggest that yoga may have a role as an adjuvant therapy in the management of autonomic dysfunction in patients with refractory epilepsy.

    To assess incidence and degree of regrowth in glioblastoma between surgery and radiation therapy (RT) and to correlate regrowth with presurgical imaging and survival, we examined images of 32 patients with newly diagnosed glioblastoma who underwent MR spectroscopic imaging (MRSI), perfusion-weighted imaging (PWI), and diffusion-weighted imaging (DWI) prior to surgery, after surgery, and prior to RT/temozolomide. Contrast enhancement (CE) in the pre-RT MR image was compared with postsurgical DWI to differentiate tumor growth from postsurgical infarct. MRSI and PWI parameters were analyzed prior to surgery and pre-RT. Postsurgical MRI indicated that 18 patients had gross total and 14 subtotal resections. Twenty-one patients showed reduced diffusion, and 25 patients showed new or increased CE. In eight patients (25%), the new CE was confined to areas of postsurgical reduced diffusion. In the other 17 patients (53%), new CE was found to be indicative of tumor growth or a combination of tumor growth and surgical injury. Higher perfusion and creatine within nonenhancing tumor in the presurgery MR were associated with subsequent tumor growth. High levels of choline and reduced diffusion in pre-RT CE suggested active metabolism and tumor cell proliferation. Median survival was 14.6 months in patients with interim tumor growth and 24 months in patients with no growth. Increased volume or new onset of CE between surgery and RT was attributed to tumor growth in 53% of patients and was associated with shorter survival. This suggests that reducing the time between surgery and adjuvant therapy may be important. The acquisition of metabolic and physiologic imaging data prior to adjuvant therapy may also be valuable in assessing regions of new CE and nonenhancing tumor. PMID:19229057

    Endometrial cancer is a common gynecologic malignancy typically diagnosed at early stage and cured with surgery alone. Adjuvant therapy is tailored according to the risk of recurrence, estimated based on the International Federation of Gynecology and Obstetrics (FIGO) stage and other histological factors. The objective of this manuscript is to review the evidence guiding adjuvant therapy for early stage and locally advanced uterine cancer. For patients with early stage disease, minimizing toxicity, while preserving outstanding cure rates remains the major goal. For patients with locally advanced endometrial cancer optimal combined regimens are being defined. Risk stratification based on molecular traits is under development and may aid refine the current risk prediction model and permit personalized approaches for women with endometrial cancer.

    Background Cardiotoxicity is an important side effect of trastuzumab therapy and cardiac surveillance is recommended. Objectives The aim of our study was to prospectively assess baseline patients' characteristics, level of N-terminal pro-brain natriuretic peptide (NT-proBNP) and echocardiographic parameters as possible predictors of trastuzumab-related cardiac dysfunction. Methods In a prospective cohort study, clinical, echocardiographic and neurohumoral assessment was performed at baseline, after 4, 8 and 12 months in breast cancer patients undergoing post-anthracycline (3-4 cycles) adjuvant therapy with trastuzumab. Trastuzumab-related cardiac dysfunction was defined as a decline of ≥ 10% in left ventricular ejection fraction (LVEF). Results 92 patients (mean age, 53.6 ± 9.0 years) were included. Patients who developed trastuzumab-related LVEF decline ≥ 10% (20.6%) during treatment had significantly higher baseline LVEF (70.7 ± 4.4%) than those without (64.8 ± 5.5%) (p = 0.0035). All other measured baseline parameters (age, body mass index, arterial hypertension, level of NT-proBNP and other echocardiographic parameters) were not identified as significant. Conclusions Our findings suggest that baseline patient' characteristics, level of NT-proBNP and echocardiographic parameters, as long as they are within normal range, are not a reliable tool to predict early trastuzumab-related cardiac dysfunction in patients undergoing post-low dose anthracycline adjuvant trastuzumab therapy. A LVEF decline in patients with high-normal baseline level although statistically significant is not clinically relevant. PMID:27305108

    Purpose: To evaluate the association between the interval from breast-conserving surgery (BCS) to radiotherapy (RT) and the clinical outcome among patients treated with adjuvant endocrine therapy. Patients and Methods: Patient information was obtained from three International Breast Cancer Study Group trials. The analysis was restricted to 964 patients treated with BCS and adjuvant endocrine therapy. The patients were divided into two groups according to the median number of days between BCS and RT and into four groups according to the quartile of time between BCS and RT. The endpoints were the interval to local recurrence, disease-free survival, and overall survival. Proportional hazards regression analysis was used to perform comparisons after adjustment for baseline factors. Results: The median interval between BCS and RT was 77 days. RT timing was significantly associated with age, menopausal status, and estrogen receptor status. After adjustment for these factors, no significant effect of a RT delay {<=}20 weeks was found. The adjusted hazard ratio for RT within 77 days vs. after 77 days was 0.94 (95% confidence interval [CI], 0.47-1.87) for the interval to local recurrence, 1.05 (95% CI, 0.82-1.34) for disease-free survival, and 1.07 (95% CI, 0.77-1.49) for overall survival. For the interval to local recurrence the adjusted hazard ratio for {<=}48, 49-77, and 78-112 days was 0.90 (95% CI, 0.34-2.37), 0.86 (95% CI, 0.33-2.25), and 0.89 (95% CI, 0.33-2.41), respectively, relative to {>=}113 days. Conclusion: A RT delay of {<=}20 weeks was significantly associated with baseline factors such as age, menopausal status, and estrogen-receptor status. After adjustment for these factors, the timing of RT was not significantly associated with the interval to local recurrence, disease-free survival, or overall survival.

    Background Aromatase inhibitor (AI) therapy results in substantial survival benefits in hormone receptor-positive breast cancer. Poor adherence and discontinuation rates of AI therapy are high, primarily due to treatment-related toxicities such as musculoskeletal pain. While pain-related symptoms may worsen during AI therapy, we hypothesized that non-persistence with AI therapy was associated with symptoms which were present prior to treatment initiation. Methods Postmenopausal women initiating AI therapy who were enrolled in a prospective clinical trial completed questionnaires at baseline to assess sleep, fatigue, mood, and pain. Reasons for treatment discontinuation during the first year of treatment were recorded. Associations between baseline patient-reported symptoms and treatment discontinuation due to toxicity were identified using logistic regression. Results Four hundred forty-nine patients were evaluable. Odds of treatment discontinuation were higher in patients who reported a greater number of symptoms prior to AI initiation. Baseline poor sleep quality was associated with early treatment discontinuation, with an odds ratio (OR) of 1.91 (95% CI 1.26–2.89; p=0.002). Baseline presence of tired feeling and forgetfulness had similar odds ratios for discontinuation (OR 1.76 (95% CI 1.15–2.67, p=0.009) and OR 1.66 (95% CI 1.11–2.48, p=0.015), respectively). Increasing total number of baseline symptoms was associated with increased likelihood of treatment discontinuation, with an OR 1.89 (95% CI 1.20–2.96; p=0.006) for 3–5 symptoms versus 0–2 symptoms. Conclusions Symptom clusters in breast cancer survivors present prior to initiation of adjuvant AI therapy may negatively impact persistence with therapy. Interventions to manage these symptoms may improve breast cancer outcomes and quality of life. PMID:24802413

    Treatment with aromatase inhibitors for postmenopausal women with breast cancer has been shown to reduce or obviate invasive procedures such as hysteroscopy or curettage associated with tamoxifen-induced endometrial abnormalities. The side effect of upfront aromatase inhibitors, diminished estrogen synthesis, is similar to that seen with the natural events of aging. The consequences often include vasomotor symptoms (hot flushes) and vaginal dryness and atrophy, which in turn may result in cystitis and vaginitis. Not surprisingly, painful intercourse (dyspareunia) and loss of sexual interest (decreased libido) frequently occur as well. Various interventions, both non-hormonal and hormonal, are currently available to manage these problems. The purpose of the present review is to provide the practitioner with a wide array of management options to assist in treating the sexual consequences of aromatase inhibitors. The suggestions in this review are based on recent literature and on the recommendations set forth both by the North American Menopause Association and in the clinical practice guidelines of the Society of Gynaecologists and Obstetricians of Canada. The complexity of female sexual dysfunction necessitates a biopsychosocial approach to assessment and management alike, with interventions ranging from education and lifestyle changes to sexual counselling, pelvic floor therapies, sexual aids, medications, and dietary supplements—all of which have been reported to have a variable, but often successful, effect on symptom amelioration. Although the use of specific hormone replacement—most commonly local estrogen, and less commonly, systemic estrogen with or without an androgen, progesterone, or the additional of an androgen in an estrogenized woman (or a combination)—may be highly effective, the concern remains that in patients with estrogen-dependent breast cancer, including those receiving anti-estrogenic adjuvant therapies, the use of these hormones may be

    Adjuvant radiation therapy by the brachytherapy technique has been suggested by us to diminish local recurrence following resection of extremity and superficial truncal soft-tissue sarcoma. However, loading of the catheters with radioactive sources on the first through the fifth postoperative days results in a 48% significant wound-complication rate. Our previous animal experiments would suggest that delay of application of radiation to one week after wounding is accompanied by significant improvement in wound-breaking strength, new H3 hydroxyproline accumulation, and improved force-tension curves. As part of our ongoing prospective randomized trial of the effects of brachytherapy on local control, one change was made: the catheters were loaded five or more days after operation. Wound complications were then reviewed in 50 patients following this single change in brachytherapy delivery. Of the 21 patients receiving brachytherapy, 14% had significant wound complications; 10% of the 29 patients who did not receive radiation had wound complications of similar severity. This decrease in wound complications represents a major improvement over our prior experience and suggests that the timing of radioactive source loading in the postoperative period is a major factor in radiation-induced wound-healing delay.

    Background: Following radical prostatectomy, success of adjuvant and salvage radiation therapy (RT) is dependent on the absence of micrometastatic disease. However, reliable prognostic/predictive factors for determining this are lacking. Therefore, novel biomarkers are needed to assist with clinical decision-making in this setting. Enumeration of circulating tumor cells (CTCs) using the regulatory-approved CellSearch System (CSS) is prognostic in metastatic prostate cancer. We hypothesize that CTCs may also be prognostic in the post-prostatectomy setting. Methods: Patient blood samples (n=55) were processed on the CSS to enumerate CTCs at 0, 6, 12 and 24 months after completion of RT. CTC values were correlated with predictive/prognostic factors and progression-free survival. Results: CTC status (presence/absence) correlated significantly with positive margins (increased likelihood of CTCneg disease; P=0.032), and trended toward significance with the presence of seminal vesicle invasion (CTCpos; P=0.113) and extracapsular extension (CTCneg; P=0.116). Although there was a trend toward a decreased time to biochemical failure (BCF) in baseline CTC-positive patients (n=9), this trend was not significant (hazard ratio (HR)=0.3505; P=0.166). However, CTC-positive status at any point (n=16) predicted for time to BCF (HR=0.2868; P=0.0437). Conclusions: One caveat of this study is the small sample size utilized (n=55) and the low number of patients with CTC-positive disease (n=16). However, our results suggest that CTCs may be indicative of disseminated disease and assessment of CTCs during RT may be helpful in clinical decision-making to determine, which patients may benefit from RT versus those who may benefit more from systemic treatments.

    Purpose: Adrenocortical carcinoma (ACC) is a rare malignancy known for high rates of local recurrence, though the benefit of postoperative radiation therapy (RT) has not been established. In this study of grossly resected ACC, we compare local control of patients treated with surgery followed by adjuvant RT to a matched cohort treated with surgery alone. Methods and Materials: We retrospectively identified patients with localized disease who underwent R0 or R1 resection followed by adjuvant RT. Only patients treated with RT at our institution were included. Matching to surgical controls was on the basis of stage, surgical margin status, tumor grade, and adjuvant mitotane. Results: From 1991 to 2011, 360 ACC patients were evaluated for ACC at the University of Michigan (Ann Arbor, MI). Twenty patients with localized disease received postoperative adjuvant RT. These were matched to 20 controls. There were no statistically significant differences between the groups with regard to stage, margins, grade, or mitotane. Median RT dose was 55 Gy (range, 45-60 Gy). Median follow-up was 34 months. Local recurrence occurred in 1 patient treated with RT, compared with 12 patients not treated with RT (P=.0005; hazard ratio [HR] 12.59; 95% confidence interval [CI] 1.62-97.88). However, recurrence-free survival was no different between the groups (P=.17; HR 1.52; 95% CI 0.67-3.45). Overall survival was also not significantly different (P=.13; HR 1.97; 95% CI 0.57-6.77), with 4 deaths in the RT group compared with 9 in the control group. Conclusions: Postoperative RT significantly improved local control compared with the use of surgery alone in this case-matched cohort analysis of grossly resected ACC patients. Although this retrospective series represents the largest study to date on adjuvant RT for ACC, its findings need to be prospectively confirmed.

    Background & Aims Recent observational studies showed that post-operative aspirin use reduces cancer relapse and death in the earliest stages of colorectal cancer. We sought to evaluate the cost-effectiveness of aspirin as an adjuvant therapy in Stage I and II colorectal cancer patients aged 65 years and older. Methods Two five-state Markov models were constructed separately for Stage I and II colorectal cancer using TreeAge Pro 2014. Two hypothetical cohorts of 10,000 individuals at a starting age of 65 years and with colorectal cancer in remission were put through the models separately. Cost-effectiveness of aspirin was evaluated against no treatment (Stage I and II) and capecitabine (Stage II) over a 20-year period from the United States societal perspective. Extensive one-way sensitivity analyses and multivariable Probabilistic Sensitivity Analyses (PSA) were performed. Results In the base case analyses, aspirin was cheaper and more effective compared to other comparators in both stages. Sensitivity analyses showed that no treatment and capecitabine (Stage II only) can be cost-effective alternatives if the utility of taking aspirin is below 0.909, aspirin’s annual fatal adverse event probability exceeds 0.57%, aspirin’s relative risk of disease progression is 0.997 or more, or when capecitabine’s relative risk of disease progression is less than 0.228. Probabilistic Sensitivity Analyses (PSA) further showed that aspirin could be cost-effective 50% to 80% of the time when the willingness-to-pay threshold was varied from USD20,000 to USD100,000. Conclusion Even with a modest treatment benefit, aspirin is likely to be cost-effective in Stage I and II colorectal cancer, thus suggesting a potential unique role in secondary prevention in this group of patients.

    High risk surgically resected melanoma is associated with a less than 50% 5-year survival. Adjuvant therapy is an appropriate treatment modality in this setting, and is more likely to be effective as the tumour burden here is small. Clinical observations of spontaneous tumour regressions and a highly variable rate of disease progression suggest a role of the immune system in the natural history of melanoma. Biological agents have therefore been the subjects of numerous adjuvant studies. Early, randomised controlled trials (RCTs) of Bacillus Calmette-Guerin (BCG), levamisole, Corynebacterium parvum, chemotherapy, isolated limb perfusion (ILP), radiotherapy, transfer factor (TF), megestrol acetate and vitamin A yielded largely negative results. Current trials focus on vaccines and the interferons. To date the latter is the only therapy to have shown a significant benefit in the prospective randomised controlled phase III setting. This report represents a systematic review of studies in adjuvant therapy in melanoma. Data from ongoing studies is awaited before a role for adjuvant agents in high risk melanoma is confirmed.

    This study assessed the relationship between pharmacological regimens at hospital discharge and hospital readmission among schizophrenia patients. The records reviewed were all consecutive admissions (N=720) from a specific catchment area during the period 1991-2005. Two main groups were selected for analysis: the first group (N=537) included patients discharged with first-generation antipsychotics (FGA), and the second group (N=183) included patients with second-generation antipsychotics (SGA). Data on clinical and demographic characteristics at discharge, including a brief psychiatric rating scale and pharmacological treatment, were collected. The rate of readmission within 12 months was analyzed in relation to the specific pharmacological treatment at discharge. There was no significant difference in the risk of readmission in patients treated with SGA compared with FGA. Adjuvant psychotropic medications to either FGA or SGA did not attenuate the risk of readmission. The readmission rate in patients treated with clozapine (N=74) was significantly lower in comparison with depot FGA (N=293) medications (P=0.016). There was no advantage of SGA over FGA, with or without adjuvant psychotropic treatment, with regard to rehospitalization risk during the 12-month follow-up. Clozapine was found to reduce the risk for readmission in comparison with depot FGA. PMID:22466059

    ABSTRACT The recurrence rates of Hepatocellular carcinoma (HCC) are high, necessitating novel and effective adjuvant therapies. Therefore, we conducted a phase II study of glypican-3 (GPC3) peptide vaccine as an adjuvant therapy for HCC patients. Forty-one patients with initial HCC who had undergone surgery or radiofrequency ablation (RFA) were analyzed in this phase II, open-label, single-arm trial. Ten vaccinations were performed for 1 y after curative treatment. We also investigated case-control subjects, where selected patients treated surgically during the same period were analyzed. The expression of GPC3 in the available primary tumors was determined by immunohistochemical analysis. Six patients received RFA therapy while 35 received surgery. The recurrence rate tended to be lower in the 35 patients treated with surgery plus vaccination compared to 33 patients who underwent surgery alone (28.6% vs. 54.3% and 39.4% vs. 54.5% at 1 and 2 y, respectively; p = 0.346, 0.983). Twenty-five patients treated with surgery and vaccination had GPC3-positive tumors; the recurrence rate in this group was significantly lower compared to that in 21 GPC3-positive patients who received surgery only (24% vs. 48% and 52.4% vs. 61.9% at 1 and 2 y, respectively; p = 0.047, 0.387). The GPC3 peptide vaccine improved the 1-y recurrence rate in patients with GPC3-positive tumors. This study demonstrated that GPC3 expression by the primary tumor may be used as a biomarker in a putative larger randomized clinical trial to determine the efficacy of the GPC3-derived peptide vaccine.

    Background: The beneficial role of cabergoline as a prophylactic agent to prevent ovarian hyper stimulation syndrome (OHSS) among high-risk patients has been demonstrated in previous studies. But data for its role as a treatment for established severe OHSS is still limited. We represent the treatment results of high dose oral cabergoline in management of six patients after the syndrome is established. Case: High-dose oral cabergoline (1 mg daily for eight days) was prescribed as an adjuvant to symptomatic treatment for six hospitalized patients with established severe OHSS following infertility treatment cycles. In two cases OHSS resolved rapidly despite the occurrence of ongoing pregnancy. Conclusion: Considering the treatment outcomes of our patients, high dose cabergoline did not eliminate the need for traditional treatments, but it was a relatively effective and safe therapy in management of established severe OHSS, and prevented the increase in its severity following the occurrence of pregnancy.

    The lack of effective drugs in stage IV melanoma has impacted the effectiveness of adjuvant therapies in stage II/III disease. To date, chemotherapy, immunostimulants and vaccines have been used with minimal success. Interferon (IFN) has shown an effect on relapse-free survival (RFS) in several clinical trials; however, without a clinically significant effect on overall survival (OS). A recently conducted meta-analysis demonstrated prolongation of disease-free survival (DFS) in 7% and OS benefit in 3% of IFN-treated patients when compared with observation-only patients. There were no clear differences for the dose and duration of treatment observed. Observation is still an appropriate control arm in adjuvant clinical trials. Regional differences exist in Europe in the adjuvant use of IFN. In Northwest Europe, IFN is infrequently prescribed. In Central and Mediterranean Europe, dermatologists commonly prescribe low-dose IFN therapy for AJCC stage II and III disease. High-dose IFN regimens are not commonly used. The population of patients that may benefit from IFN needs to be further characterised, potentially by finding biomarkers that can predict response. Such studies are ongoing. PMID:19617295

    Objective: To explore the role of adjuvant chemotherapy for patients with ypT0-2N0 rectal cancer treated by preoperative chemoradiation therapy (PCRT) and radical resection. Patients and Methods: A national consortium of 10 institutions was formed, and patients with ypT0-2N0 mid- and low-rectal cancer after PCRT and radical resection from 2004 to 2009 were included. Patients were categorized into 2 groups according to receipt of additional adjuvant chemotherapy: Adj CTx (+) versus Adj CTx (−). Propensity scores were calculated and used to perform matched and adjusted analyses comparing relapse-free survival (RFS) between treatment groups while controlling for potential confounding. Results: A total of 1016 patients, who met the selection criteria, were evaluated. Of these, 106 (10.4%) did not receive adjuvant chemotherapy. There was no overall improvement in 5-year RFS as a result of adjuvant chemotherapy [91.6% for Adj CTx (+) vs 87.5% for Adj CTx (−), P=.18]. There were no differences in 5-year local recurrence and distant metastasis rate between the 2 groups. In patients who show moderate, minimal, or no regression in tumor regression grade, however, possible association of adjuvant chemotherapy with RFS would be considered (hazard ratio 0.35; 95% confidence interval 0.14-0.88; P=.03). Cox regression analysis after propensity score matching failed to show that addition of adjuvant chemotherapy was associated with improved RFS (hazard ratio 0.81; 95% confidence interval 0.39-1.70; P=.58). Conclusions: Adjuvant chemotherapy seemed to not influence the RFS of patients with ypT0-2N0 rectal cancer after PCRT followed by radical resection. Thus, the addition of adjuvant chemotherapy needs to be weighed against its oncologic benefits.

    Uracil–Tegafur (UFT), an oral fluorinated pyrimidine chemotherapeutic agent, has been used for adjuvant chemotherapy in curatively resected colorectal cancer patients. Past trials and meta-analyses indicate that it is somewhat effective in extending survival of patients with rectal cancer. The objective of this study was to perform a reappraisal of randomised clinical trials conducted in this field. We designed an individual patient-based meta-analysis of relevant clinical trials to examine the benefit of UFT for curatively resected rectal cancer in terms of overall survival (OS), disease-free survival (DFS), and local relapse-free survival (LRFS). We analysed individual patient data of five adjuvant therapy randomised clinical trials for rectal cancer, which met the predetermined inclusion criteria. These five trials had a combined total of 2091 patients, UFT as adjuvant chemotherapy compared to surgery-alone, 5-year follow-up, intention-to-treat-based analytic strategy, and similar endpoints (OS and DFS). In a pooled analysis, UFT had significant advantage over surgery-alone in terms of both OS (hazard ratio, 0.82; 95% confidence interval (CI), 0.70–0.97; P=0.02) and DFS (hazard ratio, 0.73; 95%CI, 0.63–0.84; P<0.0001). This individual patient-based meta-analysis demonstrated that oral UFT significantly improves both OS and DFS in patients with curatively resected rectal cancer. PMID:17375049

    Purpose: To assess the locoregional failure in patients with Stage I-II breast cancer treated with radical mastectomy and to evaluate whether a subset of these patients might be at sufficiently high risk of locoregional recurrence (LRR) to benefit from postmastectomy irradiation (PMRT). Methods and Materials: Stage I-II breast cancer patients (n = 150) treated with radical mastectomy without adjuvant irradiation between 1999 and 2005 were analyzed. The pattern of LRR was reported. Kaplan-Meier analysis was used to calculate rates of LRR, and Cox proportional hazards methods were used to evaluate potential risk factors. Results: Median follow-up was 75 months. Mean patient age was 56 years. One-hundred forty-three (95%) patients received adjuvant systemic therapy: 85 (57%) hormonal therapy alone, 14 (9%) chemotherapy alone, and 44 (29%) both chemotherapy and hormonal therapy. Statistically significant factors associated with increased risk of LRR were premenopausal status (p = 0.004), estrogen receptor negative cancer (p = 0.02), pathologic grade 3 (p = 0.02), and lymphovascular invasion (p = 0.001). T and N stage were not associated with increased risk of regional recurrence. The 5-year LRR rate for patients with zero or one, two, three, and four risk factors was 1%, 10.3%, 24.2%, and 75%, respectively. Conclusions: A subset of patients with early-stage breast cancer is at high risk of LRR, and therefore PMRT might be beneficial.

    Aim To evaluate the efficacy and safety of bevacizumab in the adjuvant cancer therapy setting within different subset of patients. Methods & Design/ Results PubMed, EMBASE, Cochrane and Clinical trials.gov databases were searched for English language studies of randomized controlled trials comparing bevacizumab and adjuvant therapy with adjuvant therapy alone published from January 1966 to 7th of May 2014. Progression free survival, overall survival, overall response rate, safety and quality of life were analyzed using random- or fixed-effects models according to the PRISMA guidelines. We obtained data from 44 randomized controlled trials (30,828 patients). Combining bevacizumab with different adjuvant therapies resulted in significant improvement of progression free survival (log hazard ratio, 0.87; 95% confidence interval (CI), 0.84–0.89), overall survival (log hazard ratio, 0.96; 95% CI, 0.94–0.98) and overall response rate (relative risk, 1.46; 95% CI: 1.33–1.59) compared to adjuvant therapy alone in all studied tumor types. In subgroup analyses, there were no interactions of bevacizumab with baseline characteristics on progression free survival and overall survival, while overall response rate was influenced by tumor type and bevacizumab dose (p-value: 0.02). Although bevacizumab use resulted in additional expected adverse drug reactions except anemia and fatigue, it was not associated with a significant decline in quality of life. There was a trend towards a higher risk of several side effects in patients treated by high-dose bevacizumab compared to the low-dose e.g. all grade proteinuria (9.24; 95% CI: 6.60–12.94 vs. 2.64; 95% CI: 1.29–5.40). Conclusions Combining bevacizumab with different adjuvant therapies provides a survival benefit across all major subsets of patients, including by tumor type, type of adjuvant therapy, and duration and dose of bevacizumab therapy. Though bevacizumab was associated with increased risks of some adverse drug

    The aim of this article was to review the most widely researched adjuvant medical therapies for the surgical management of urolithiasis. Articles were identified and reviewed from PubMed and Medline databases with MeSH headings focusing on the various surgical treatments of urolithiasis and adjuvant therapy. Additional articles were retrieved from references and conference proceedings. Surgical treatments reviewed included shockwave lithotripsy, ureteroscopy, and percutaneous nephrolithotomy. Adjuvant therapy was considered medical or complementary therapy as an adjunct to these surgical interventions. Adjuvant therapy for the surgical management of urolithiasis has been documented to increase stone-free rates, reduce stone remission rates, prevent renal damage, and decrease postoperative morbidity. A variety of agents have been studied, ranging from antioxidants to alpha-blockers and to alkalinizing agents. Additionally, there is increasing interest in complementary adjuvant therapy (ie, acupuncture). Adjuvant therapy is a fertile area for research in the surgical management of urolithiasis. The optimal agents have yet to be determined and therefore further investigation is warranted and necessary.

    Elevated Microsatellite Alterations at Selected Tetranucleotide repeats (EMAST) is a genetic signature found in up to 60% of colorectal cancers (CRCs) that is caused by somatic dysfunction of the DNA mismatch repair (MMR) protein hMSH3. We have previously shown in vitro that recognition of 5-fluorouracil (5-FU) within DNA and subsequent cytotoxicity was most effective when both hMutSα (hMSH2-hMSH6 heterodimer) and hMutSβ (hMSH2-hMSH3 heterodimer) MMR complexes were present, compared to hMutSα > hMutSβ alone. We tested if patients with EMAST CRCs (hMutSβ defective) had diminished response to adjuvant 5-FU chemotherapy, paralleling in vitro findings. We analyzed 230 patients with stage II/III sporadic colorectal cancers for which we had 5-FU treatment and survival data. Archival DNA was analyzed for EMAST (>2 of 5 markers mutated among UT5037, D8S321, D9S242, D20S82, D20S85 tetranucleotide loci). Kaplan-Meier survival curves were generated and multivariate analysis was used to determine contribution to risk. We identified 102 (44%) EMAST cancers. Ninety-four patients (41%) received adjuvant 5-FU chemotherapy, and median follow-up for all patients was 51 months. Patients with EMAST CRCs demonstrated improved survival with adjuvant 5FU to the same extent as patients with non-EMAST CRCs (P<0.05). We observed no difference in survival between patients with stage II/III EMAST and non-EMAST cancers (P = 0.36). There is improved survival for stage II/III CRC patients after adjuvant 5-FU-based chemotherapy regardless of EMAST status. The loss of contribution of hMSH3 for 5-FU cytotoxicity may not adversely affect patient outcome, contrasting patients whose tumors completely lack DNA MMR function (MSI-H). PMID:25996601

    Purpose: To study the impact of postoperative radiation therapy (PORT) on survival in the Adjuvant Navelbine International Trialist Association (ANITA) randomized study of adjuvant chemotherapy. Methods and Materials: ANITA is a randomized trial of adjuvant cisplatin and vinorelbine chemotherapy vs. observation in completely resected non-small-cell lung carcinoma (NSCLC) Stages IB to IIIA. Use of PORT was recommended for pN+ disease but was not randomized or mandatory. Each center decided whether to use PORT before initiation of the study. We describe here the survival of patients with and without PORT within each treatment group of ANITA. No statistical comparison of survival was performed because this was an unplanned subgroup analysis. Results: Overall, 232 of 840 patients received PORT (33.3% in the observation arm and 21.6% in the chemotherapy arm). In univariate analysis, PORT had a deleterious effect on the overall population survival. Patients with pN1 disease had an improved survival from PORT in the observation arm (median survival [MS] 25.9 vs. 50.2 months), whereas PORT had a detrimental effect in the chemotherapy group (MS 93.6 months and 46.6 months). In contrast, survival was improved in patients with pN2 disease who received PORT, both in the chemotherapy (MS 23.8 vs. 47.4 months) and observation arm (median 12.7 vs. 22.7 months). Conclusion: This retrospective evaluation suggests a positive effect of PORT in pN2 disease and a negative effect on pN1 disease when patients received adjuvant chemotherapy. The results support further evaluation of PORT in prospectively randomized studies in completely resected pN2 NSCLC.

    Purpose: To develop nomograms for predicting the overall survival (OS) and relapse-free survival (RFS) in patients with extrahepatic bile duct cancer undergoing adjuvant chemoradiation therapy after curative resection. Methods and Materials: From January 1995 through August 2006, a total of 166 consecutive patients underwent curative resection followed by adjuvant chemoradiation therapy. Multivariate analysis using Cox proportional hazards regression was performed, and this Cox model was used as the basis for the nomograms of OS and RFS. We calculated concordance indices of the constructed nomograms and American Joint Committee on Cancer (AJCC) staging system. Results: The OS rate at 2 years and 5 years was 60.8% and 42.5%, respectively, and the RFS rate at 2 years and 5 years was 52.5% and 38.2%, respectively. The model containing age, sex, tumor location, histologic differentiation, perineural invasion, and lymph node involvement was selected for nomograms. The bootstrap-corrected concordance index of the nomogram for OS and RFS was 0.63 and 0.62, respectively, and that of AJCC staging for OS and RFS was 0.50 and 0.52, respectively. Conclusions: We developed nomograms that predicted survival and recurrence better than AJCC staging. With caution, clinicians may use these nomograms as an adjunct to or substitute for AJCC staging for predicting an individual's prognosis and offering tailored adjuvant therapy.

    Purpose To explore how symptoms and psychosocial factors are related to intentional and unintentional non-adherent medication taking behaviors. Methods Included were postmenopausal women with hormone receptor positive, stage I-IIIA breast cancer, who had completed surgery, chemotherapy, and radiation, and were taking endocrine therapy. Self-administered, standardized measures were completed during a routine clinic visit: Brief Fatigue Inventory, Brief Pain Inventory, Menopause Specific Quality of Life Questionnaire, Functional Assessment of Cancer Therapy General and Neurotoxicity scales, and Self-Efficacy for Appropriate Medication Use Scale. Regression analyses were performed to determine the degree to which demographic, medical, symptom, and psychosocial variables, explain intentional, such as changing one’s doses or stopping medication, and unintentional, such as forgetting to take one’s medication, non-adherent behaviors. Results Participants were 112 women: mean age 64 (SD=9) years; 81% white; mean time from surgery 40 (SD=28) months; 49% received chemotherapy (39% including a taxane); mean time on endocrine therapy, 35 (SD=29.6) months; 82% taking an aromatase inhibitor. Intentional and unintentional non-adherent behaviors were described in 33.9% and 58.9% of participants, respectively. Multivariate analysis showed that higher self-efficacy for taking medication was associated with lower levels of unintentional (p=0.002) and intentional (p=0.004) non-adherent behaviors. The presence of symptoms (p=0.03) and lower self-efficacy for physician communication (p=0.009) were associated with higher levels of intentional non-adherent behaviors. Conclusions These results suggest that women who report greater symptoms, lower self-efficacy for communicating with their physician, and lower self-efficacy for taking their medication are more likely to engage in both intentional and unintentional non-adherent behaviors.

    Radioactive iodine (RAI) is used in treatment of patients with differentiated papillary and follicular thyroid cancer. It is typically used after thyroidectomy, both as a means of imaging to detect residual thyroid tissue or metastatic disease, as well as a means of treatment by ablation if such tissue is found. In this paper, we discuss the indications for and the mechanisms of RAI in the treatment of patients with thyroid cancer. We discuss the attendant risks and benefits that come with its use, as well as techniques used to optimize its effectiveness as an imaging tool and a therapeutic modality. PMID:23193402

    Purpose: To analyze the effect of adjuvant chemoradiotherapy on gallbladder carcinoma. Methods and Materials: We retrospectively reviewed the records from consecutive patients who underwent R0 resection of gallbladder carcinoma between January 1, 1985, and December 31, 2004. Patients had either Stage I (T1-T2N0M0) or Stage II (T3N0M0 or T1-T3N1M0) disease. Patients undergoing adjuvant therapy received 5-fluorouracil chemotherapy concurrently with radiotherapy (median dosage, 50.4 Gy in 28 fractions). Adverse prognostic factors and the effect of adjuvant treatment on overall survival (OS) were evaluated. Results: A total of 73 patients were included in the analysis; of these, 25 received adjuvant chemoradiotherapy. On univariate analysis, no adverse prognostic factors for OS reached statistical significance, but trends were noted for Stage N1 vs. N0 (p = .06), Nx vs. N0 (p = .09), Stage T3 vs. T1-T2 (p = .06), and histologic findings other than adenocarcinoma (p = .13). The median OS for patients receiving adjuvant chemoradiotherapy vs. surgery alone was 4.8 years and 4.2 years, respectively (log-rank test, p = .56). However, a significantly greater percentage of patients receiving adjuvant chemoradiotherapy had Stage II disease (p <.001). In the multivariate Cox model, increasing T and N category and histologic findings other than adenocarcinoma were significant predictors of decreased OS. Additionally, adjuvant chemoradiotherapy was a significant predictor of improved OS after adjusting for these prognostic factors (hazard ratio for death, 0.3; 95% confidence interval, 0.13-0.69; p = .004). Conclusion: After adjusting for the stage parameters and histologic findings, our data suggest that adjuvant chemoradiotherapy might improve OS for patients with gallbladder cancer.

    Since preoperative chemotherapy has been clearly shown to improve outcomes for patients with Ewing sarcoma, rhabdomyosarcoma, and osteosarcoma, practitioners have attempted to extend the use of adjuvant/neoadjuvant chemotherapy to other types of adult soft tissue sarcoma. Given the high risk of distant recurrence and disease-specific death for patients with soft tissue sarcoma tumors larger than 10 cm, these patients should be considered candidates for neoadjuvant chemotherapy as well as investigational therapies. Yet, potential toxicity from cytotoxic chemotherapy is substantial, and there remains little consensus and wide variation regarding the indications for use of chemotherapy in the adjuvant/neoadjuvant setting.

    The first 15 years of management of gastrointestinal stromal tumor (GIST) have led to 3 lines of therapy for metastatic disease: imatinib, sunitinib, and regorafenib. In the adjuvant setting, imatinib is usually given for 3 years postoperatively to patients with higher-risk primary tumors that are completely resected. In this review, issues regarding GIST adjuvant therapy are discussed. It is hoped this review will help the reader understand the present standard of care to improve upon it in years to come.

    RA is an autoimmune rheumatic disorder resulting from the combination of several predisposing factors, including the relation between epitopes of possible triggering agents and histocompatibility epitopes, the status of the stress response system, and the sex hormone status. Estrogens are implicated as enhancers of humoral immunity, and androgens and progesterone are natural immune suppressors. Sex hormone concentrations have been evaluated in RA patients before glucocorticoid therapy and have frequently been found to be altered, especially in premenopausal women and male patients. In particular, low levels of gonadal and adrenal androgens (testosterone and DHT, DHEA and DHEAS) and a reduced androgen:estrogen ratio have been detected in body fluids (i.e., blood, synovial fluid, smears, saliva) of male and female RA patients. These observations support a possible pathogenic role for the decreased levels of the immune-suppressive androgens. Exposure to environmental estrogens (estrogenic xenobiotics), genetic polymorphisms of genes coding for hormone metabolic enzymes or receptors, and gonadal disturbances related to stress system activation (hypothalamic-pituitary-adrenocortical axis) and physiologic hormonal perturbations such as during aging, the menstrual cycle, pregnancy, the postpartum period, and menopause may interfere with the androgen:estrogen ratio. Sex hormones might exert their immune-modulating effects, at least in RA synovitis, because synovial macrophages, monocytes, and lymphocytes possess functional androgen and estrogen receptors and may metabolize gonadal hormones. The molecular basis for sex hormone adjuvant therapy in RA is thus experimentally substantiated. By considering the well-demonstrated immune-suppressive activities exerted by androgens, male hormones and their derivatives seem to be the most promising therapeutic approach. Recent studies have shown positive effects of androgen replacement therapy at least in male RA patients

    Statins have been shown to decrease depressive symptoms in certain groups of patients, an effect that is mostly attributed to their anti-inflammatory and neurotransmitter modulatory potentials. We aimed to investigate the antidepressant effects of simvastatin as an adjuvant therapy in patients with moderate to severe depression. In this double-blind placebo-controlled clinical trial, 48 patients were randomly allocated to receive simvastatin or placebo as an adjunct to fluoxetine for six weeks. Patients were evaluated with the Hamilton Depression Rating Scale (HDRS) at baseline and weeks 2, 4 and 6. Probable clinical and laboratory adverse events were also monitored and compared between the two groups. Simvastatin-treated patients experienced significantly more reductions in HDRS scores compared to the placebo group by the end of the trial (p=0.02). Early improvement and response rates were significantly greater in the simvastatin group than the placebo group (p=0.02 and p=0.01, respectively) but remission rate was not significantly different between the two groups (p=0.36). No serious adverse event was reported during this trial. In conclusion, simvastatin seems to be a safe and effective adjuvant therapy for patients suffering from major depressive disorder. However, more confirmatory studies are warranted.

    Purpose: To study the impact of dose fractionation of adjuvant radiation therapy (RT) on local recurrence (LR) and the relation of LR to radiation fields. Methods and Materials: LR rates were analyzed in 462 adult patients with soft tissue sarcoma who underwent surgical excision and adjuvant RT at five Scandinavian sarcoma centers from 1998 to 2009. Medical records were reviewed for dose fractionation parameters and to determine the location of the LR relative to the radiation portals. Results: Fifty-five of 462 patients developed a LR (11.9%). Negative prognostic factors included intralesional surgical margin (hazard ratio [HR]: 7.83, 95% confidence interval [CI]: 3.08-20.0), high malignancy grade (HR: 5.82, 95% CI: 1.31-25.8), age at diagnosis (HR per 10 years: 1.27, 95% CI: 1.03-1.56), and malignant peripheral nerve sheath tumor histological subtype (HR: 6.66, 95% CI: 2.56-17.3). RT dose was tailored to margin status. No correlation between RT dose and LR rate was found in multiple Cox regression analysis. The majority (65%) of LRs occurred within the primary RT volume. Conclusions: No significant dose–response effect of adjuvant RT was demonstrated. Interestingly, patients given 45-Gy accelerated RT (1.8 Gy twice daily/2.5 weeks) had the best local outcome. A total dose of 50 Gy in 25 fractions seemed adequate following wide margin surgery. The risk of LR was associated with histopathologic subtype, which should be included in the treatment algorithm of adjuvant RT in soft tissue sarcoma.

    Endocrine treatment plays a pivotal role in the adjuvant therapy of patients harbouring oestrogen and/or progesterone receptor positive breast cancer. The objective of this paper is to critically review endocrine treatment options in early breast cancer focusing on ongoing development. Literature was collected through the ISI Web of Science and PubMed in January/February 2009 with subsequent update by December 2009, using the words breast cancer, endocrine therapy, oestrogen receptor and aromatase. Endocrine therapy improves outcome in early breast cancer. Yet several controversies remain. There has recently been a lack of general consensus regarding the limit of oestrogen receptor positivity. As for adjuvant therapy in general and use of aromatase inhibitors in particular, we need the results from ongoing studies to decide what may be the optimal duration of therapy and regimen (sequential treatment versus monotherapy; one drug compared with another). Further, there is a need to critically assess optimal use of endocrine therapy for metastatic disease among patients previously exposed to endocrine regimens in the adjuvant setting. While in general the mechanisms of resistance to endocrine therapy among ER positive tumours remains unknown, merging evidence suggest a role of different growth factor pathways, in particular HER-2 activation. Thus, particular attention is paid to the topic of HER-2 expression as a potential cause of endocrine resistance.

    Most breast cancers are hormone receptor positive and exhibit a slow growth pattern. Based on biological properties, breast cancers are divided into four different biological subtypes. Furthermore, these subtypes are indicative of the risk of recurrence, which is also influenced by the size of the tumor and extension to lymph nodes. Postoperative adjuvant drug therapy is chosen on the basis of the biological type. Chemotherapy can be used in all subtypes. Hormonal therapies are used exclusively for the treatment of hormone receptor positive breast cancer. Trastuzumab antibody belongs to the treatment of the HER2 positive subtype. PMID:26245052

    CytoSorb(®) (CytoSorbents Corporation, USA) is a novel sorbent hemoadsorption device for cytokine removal. The aim of this study was to examine the clinical use of CytoSorb(®) in the management of patient with septic shock. We used this device as an adjuvant to stabilize a young patient with multi-organ failure and severe sepsis with septic shock. A 36-year-old female patient was hospitalized with the complaints of malaise, general body ache, and breathing difficulty and had a medical history of diabetes mellitus type II, hypertension, obstructive sleep apnea, hypothyroidism and morbid obesity. She was diagnosed to have septic shock with multi-organ dysfunction (MODS) and a low perfusion state. CytoSorb(®) hemoadsorption column was used as an attempt at blood purification. Acute physiology and chronic health evaluation score, MODS score, and sequential organ failure assessment score were measured before and after the device application. CytoSorb application as an adjuvant therapy could be considered in septic shock.

    Breast cancer patients are considered to be at relatively low risk of developing a TEE. The highest incidence of VTE events occurs in metastatic breast cancer patients likely due to extension of disease, immobility for pathologic bone fractures, cancer cachexia and venous compression by the tumour mass. Although thrombosis is less common in patients with early stage cancer compared to those with more advanced disease, it does occur and is clinically challenging. The adjuvant setting is of particular interest in order to assess the specific thrombogenic potential of systemic chemotherapy, because of the low tumor burden with only microscopic tumor foci at the time of treatment administration. This review summarizes risk factors, incidence and strategies to avoid VTE in breast cancer patients receiving adjuvant therapy.

    Background: Postoperative radiation therapy for stage I endometrial cancer improves locoregional control but is without survival benefit. To facilitate treatment decision support for individual patients, accurate statistical models to predict locoregional relapse (LRR), distant relapse (DR), overall survival (OS), and disease-free survival (DFS) are required. Methods and Materials: Clinical trial data from the randomized Post Operative Radiation Therapy for Endometrial Cancer (PORTEC-1; N=714 patients) and PORTEC-2 (N=427 patients) trials and registered group (grade 3 and deep invasion, n=99) were pooled for analysis (N=1240). For most patients (86%) pathology review data were available; otherwise original pathology data were used. Trial variables which were clinically relevant and eligible according to data constraints were age, stage, given treatment (pelvic external beam radiation therapy (EBRT), vaginal brachytherapy (VBT), or no adjuvant treatment, FIGO histological grade, depth of invasion, and lymph-vascular invasion (LVSI). Multivariate analyses were based on Cox proportional hazards regression model. Predictors were selected based on a backward elimination scheme. Model results were expressed by the c-index (0.5-1.0; random to perfect prediction). Two validation sets (n=244 and 291 patients) were used. Results: Accuracy of the developed models was good, with training accuracies between 0.71 and 0.78. The nomograms validated well for DR (0.73), DFS (0.69), and OS (0.70), but validation was only fair for LRR (0.59). Ranking of variables as to their predictive power showed that age, tumor grade, and LVSI were highly predictive for all outcomes, and given treatment for LRR and DFS. The nomograms were able to significantly distinguish low- from high-probability patients for these outcomes. Conclusions: The nomograms are internally validated and able to accurately predict long-term outcome for endometrial cancer patients with observation, pelvic EBRT, or VBT

  7. Evaluation of six CTLA-4 polymorphisms in high-risk melanoma patients receiving adjuvant interferon therapy in the He13A/98 multicenter trial

    2010-01-01

    Purpose Interferon is approved for adjuvant treatment of patients with stage IIb/III melanoma. The toxicity and uncertainty regarding survival benefits of interferon have qualified its acceptance, despite significant durable relapse prevention in a fraction of patients. Predictive biomarkers that would enable selection of patients for therapy would have a large impact upon clinical practice. Specific CTLA-4 polymorphisms have previously shown an association with response to CTLA-4 blockade in patients with metastatic melanoma and the development of autoimmunity. Experimental design 286 melanoma patients and 288 healthy controls were genotyped for six CTLA-4 polymorphisms previously suggested to be important (AG 49, CT 318, CT 60, JO 27, JO30 and JO 31). Specific allele frequencies were compared between the healthy and patient populations, as well as presence or absence of these in relation to recurrence. Alleles related to autoimmune disease were also investigated. Results No significant differences were found between the distributions of CTLA-4 polymorphisms in the melanoma population compared with healthy controls. Relapse free survival (RFS) and overall survival (OS) did not differ significantly between patients with the alleles represented by these polymorphisms. No correlation between autoimmunity and specific alleles was shown. The six polymorphisms evaluated where strongly associated (Fisher's exact p-values < 0.001 for all associations) and significant linkage disequilibrium among these was indicated. Conclusion No polymorphisms of CTLA-4 defined by the SNPs studied were correlated with improved RFS, OS, or autoimmunity in this high-risk group of melanoma patients. PMID:21044351

    Purpose To assess the impact of patient-provider communication on adherence to tamoxifen (TAM) and aromatase inhibitors (AI) 36 months after breast cancer (BC) diagnosis in a low-income population of women. Methods California statewide surveys were conducted among 921 low-income women with BC at 6-, 18-, and 36-months after BC diagnosis. A subset of 303 women with stage I–III BC who initiated hormone treatment after diagnosis was identified. Bivariate and multivariate logistic regression analyses were performed, and adjusted adherence rates were calculated. The main outcome measure was self-reported hormone use at 36 months after BC diagnosis and the chief independent variables were patient-centered communication after diagnosis by patient report as measured by the Consumer Assessment of Healthcare Providers and Systems (CAHPS) and patients’ self-efficacy in patient-physician interactions (PEPPI). Results Overall adherence to TAM/AI was relatively high (88%). Adjusted rates of adherence were 59% and 94% for patients with the lowest vs. highest scores on the CAHPS communication scale (AOR=1.22, P=0.006) and 72% vs. 91% for patients with the lowest and highest rating of PEPPI (AOR=1.04, P=0.04). Having at least one comorbid condition also increased the odds of adherence to hormonal therapy (AOR=3.14, P=0.03). Having no health insurance and experiencing side-effects from hormone treatment were barriers for adherence (AOR=0.12, P=0.001; AOR=0.26, P=0.003, respectively). Conclusions Patient-centered communication and perceived self-efficacy in patient-physician interaction were significantly associated with patient adherence to ongoing TAM/AI therapy among low-income women with BC. Interventions on patient-provider communication may provide opportunities to improve patient outcomes in this vulnerable population. PMID:23263740

    In gastric adenocarcinoma, high rates of loco-regional recurrences have been reported even after complete resection, and various studies have been tried to find the role of postoperative adjuvant therapy. Among them, Intergroup 0116 trial was a landmark trial, and demonstrated the definite survival benefit in adjuvant chemoradiotherapy, compared with surgery alone. However, the INT 0116 trial had major limitation for global acceptance of the INT 0116 regimen as an adjuvant treatment modality because of the limited lymph node dissection. Lately, several randomized studies that were performed to patients with D2-dissected gastric cancer were published. This review summarizes the data about patterns of failure after surgical resection and the earlier prospective studies, including INT 0116 study. Author will introduce the latest studies, including ARTIST trial and discuss whether external beam radiotherapy should be applied to patients receiving extended lymph node dissection and adjuvant chemotherapy.

    Purpose: We used the Female Sexual Function Index (FSFI) to investigate the prevalence of sexual dysfunction (SD) and factors associated with diminished sexual functioning in early stage endometrial cancer (EC) patients treated with simple hysterectomy and adjuvant brachytherapy. Methods and Materials: A cohort of 104 patients followed in a radiation oncology clinic completed questionnaires to quantify current levels of sexual functioning. The time interval between hysterectomy and questionnaire completion ranged from <6 months to >5 years. Multivariate regression was performed using the FSFI as a continuous variable (score range, 1.2-35.4). SD was defined as an FSFI score of <26, based on the published validation study. Results: SD was reported by 81% of respondents. The mean ({+-} standard deviation) domain scores in order of highest-to-lowest functioning were: satisfaction, 2.9 ({+-}2.0); orgasm, 2.5 ({+-}2.4); desire, 2.4 ({+-}1.3); arousal, 2.2 ({+-}2.0); dryness, 2.1 ({+-}2.1); and pain, 1.9 ({+-}2.3). Compared to the index population in which the FSFI cut-score was validated (healthy women ages 18-74), all scores were low. Compared to published scores of a postmenopausal population, scores were not statistically different. Multivariate analysis isolated factors associated with lower FSFI scores, including having laparotomy as opposed to minimally invasive surgery (effect size, -7.1 points; 95% CI, -11.2 to -3.1; P<.001), lack of vaginal lubricant use (effect size, -4.4 points; 95% CI, -8.7 to -0.2, P=.040), and short time interval (<6 months) from hysterectomy to questionnaire completion (effect size, -4.6 points; 95% CI, -9.3-0.2; P=.059). Conclusions: The rate of SD, as defined by an FSFI score <26, was prevalent. The postmenopausal status of EC patients alone is a known risk factor for SD. Additional factors associated with poor sexual functioning following treatment for EC included receipt of laparotomy and lack of vaginal lubricant use.

    Purpose: Large randomized trials have demonstrated significant survival benefits with the use of adjuvant chemotherapy or chemoradiation therapy for gastric cancer. The importance of adjuvant radiation therapy (RT) remains unclear. We performed an up-to-date meta-analysis of randomized trials testing the use of RT for resectable gastric cancer. Methods and Materials: We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials for randomized trials testing adjuvant (including neoadjuvant) RT for resectable gastric cancer. Hazard ratios describing the impact of adjuvant RT on overall survival (OS) and disease-free survival (DFS) were extracted directly from the original studies or calculated from survival curves. Pooled estimates were obtained using the inverse variance method. Subgroup analyses were performed to determine whether the efficacy of RT varies with chemotherapy use, RT timing, geographic region, type of nodal dissection performed, or lymph node status. Results: Thirteen studies met all inclusion criteria and were used for this analysis. Adjuvant RT was associated with a significant improvement in both OS (HR = 0.78, 95% CI: 0.70-0.86, P<.001) and DFS (HR = 0.71, 95% CI: 0.63-0.80, P<.001). In the 5 studies that tested adjuvant chemoradiation therapy against adjuvant chemotherapy, similar effects were seen for OS (HR = 0.83, 95% CI: 0.67-1.03, P=.087) and DFS (HR = 0.77, 95% CI: 0.91-0.65, P=.002). Available data did not reveal any subgroup of patients that does not benefit from adjuvant RT. Conclusion: In randomized trials for resectable gastric cancer, adjuvant RT provides an approximately 20% improvement in both DFS and OS. Available data do not reveal a subgroup of patients that does not benefit from adjuvant RT. Further study is required to optimize the implementation of adjuvant RT for gastric cancer with regard to patient selection and integration with systemic therapy.

    Many studies are dedicated to exploring the molecular mechanisms of chemotherapy-resistance in breast cancer (BC). Some of them are focused on searching for candidate genes responsible for this process. The aim of this study was typing the candidate genes associated with the response to standard chemotherapy in the case of invasive ductal carcinoma. Frozen material from 28 biopsies obtained from IDC patients with different responses to chemotherapy were examined using gene expression microarray, Real-Time PCR (RT-PCR) and Western blot (WB). Based on the microarray results, further analysis of candidate gene expression was evaluated in 120 IDC cases by RT-PCR and in 224 IDC cases by immunohistochemistry (IHC). The results were correlated with clinical outcome and molecular subtype of the BC. Gene expression microarray revealed Prolactin-Induced Peptide (PIP) as a single gene differentially expressed in BC therapy responder or non-responder patients (p <0.05). The level of PIP expression was significantly higher in the BC therapy responder group than in the non-responder group at mRNA (p=0.0092) and protein level (p=0.0256). Expression of PIP mRNA was the highest in estrogen receptor positive (ER+) BC cases (p=0.0254) and it was the lowest in triple negative breast cancer (TNBC) (p=0.0336). Higher PIP mRNA expression was characterized by significantly longer disease free survival (DFS, p=0.0093), as well as metastasis free survival (MFS, p=0.0144). Additionally, PIP mRNA and PIP protein expression levels were significantly higher in luminal A than in other molecular subtypes and TNBC. Moreover significantly higher PIP expression was observed in G1, G2 vs. G3 cases (p=0.0027 and p=0.0013, respectively). Microarray analysis characterized PIP gene as a candidate for BC standard chemotherapy response marker. Analysis of clinical data suggests that PIP may be a good prognostic and predictive marker in IDC patients. Higher levels of PIP were related to longer DFS and MFS

    Breast cancer in the elderly is an increasing clinical problem. In addition, ~60% of deaths from breast cancer occur in women aged 65 years and older. Despite this, older women with breast cancer have been underrepresented in clinical trials, and this has led to less than optimal evidence to guide their therapy. The management of elderly women with early breast cancer is a complex process that requires careful evaluation of life expectancy, comorbidities, patient values, and risks and benefits of available treatment options. This review will focus on current adjuvant systemic therapy options for older women with breast cancer, discuss the principles in the decision-making process, and define the role of endocrine therapy, chemotherapy, and targeted agents.

    Purpose: To describe the quality of life (QOL) in elderly patients with glioblastoma (GBM) treated with an abbreviated course of radiation therapy (RT; 40 Gy in 15 fractions) plus concomitant and adjuvant temozolomide (TMZ). Methods and Materials: Health-related QOL (HRQOL) was assessed by European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core-30 (QLQ-C30, version 3) and EORTC Quality of Life Questionnaire Brain Cancer Module (QLQ-BN20). Changes from baseline in the score of 9 preselected domains (global QLQ, social functioning, cognitive functioning, emotional functioning, physical functioning, motor dysfunction, communication deficit, fatigue, insomnia) were determined 4 weeks after RT and thereafter every 8 weeks during the treatment until disease progression. The proportion of patients with improved HRQOL scores, defined as a change of 10 points or more, and duration of changes were recorded. Results: Sixty-five patients completed the questionnaires at baseline. The treatment was consistently associated with improvement or stability in most of the preselected HRQOL domains. Global health improved over time; mean score differed by 9.6 points between baseline and 6-month follow-up (P=.03). For social functioning and cognitive functioning, mean scores improved over time, with a maximum difference of 10.4 points and 9.5 points between baseline and 6-month follow-up (P=.01 and P=.02), respectively. By contrast, fatigue worsened over time, with a difference in mean score of 5.6 points between baseline and 4-month follow-up (P=.02). Conclusions: A short course of RT in combination with TMZ in elderly patients with GBM was associated with survival benefit without a negative effect on HRQOL until the time of disease progression.

    2016-01-01

    Hematopoietic stem cell transplant (HSCT) using mobilized peripheral blood hematopoietic stem cells (HSPCs) is the only curative strategy for many patients suffering from hematological malignancies. HSPC collection protocols rely on pharmacological agents to mobilize HSPCs to peripheral blood. Limitations including variable donor responses and long dosing protocols merit further investigations into adjuvant therapies to enhance the efficiency of HSPCs collection. Exercise, a safe and feasible intervention in patients undergoing HSCT, has been previously shown to robustly stimulate HSPC mobilization from the bone marrow. Exercise-induced HSPC mobilization is transient limiting its current clinical potential. Thus, a deeper investigation of the mechanisms responsible for exercise-induced HSPC mobilization and the factors responsible for removal of HSPCs from circulation following exercise is warranted. The present review will describe current research on exercise and HSPC mobilization, outline the potential mechanisms responsible for exercise-induced HSPC mobilization, and highlight potential sites for HSPC homing following exercise. We also outline current barriers to the implementation of exercise as an adjuvant therapy for HSPC mobilization and suggest potential strategies to overcome these barriers. PMID:27123008

In 13 of 24 patients (54.1%), abnormal menses, including amenorrhea in 12 cases and oligomenorrhea in 1 case, developed during adjuvant therapy. In patients with abnormal menses, serum estradiol was significantly lower, and the levels of gonadotropins were significantly higher than in patients with normal menses. Among 13 patients with abnormal menses, 4 patients treated with cyclophosphamide revealed persistent amenorrhea during the whole period with adjuvant therapy, and the levels of serum estradiol and progesterone were extremely low. Furthermore, in these patients normal menses has not recovered and the levels of serum estradiol and progesterone remained low 4 to 5 months after cessation of cyclophosphamide administration. Thus, adjuvant chemotherapy caused depression of ovarian function, and cyclophosphamide induced ovarian failure, resulting in complete amenorrhea.

    Breast cancer remains the leading cause of cancer related mortality in premenopausal women. Multiple advances in local and systemic therapies have dramatically improved outcomes in women with HR+ early stage breast cancer. Despite these advances, early and late relapses occur. Therefore multiple adjuvant endocrine therapy trials have been conducted with the goal of decreasing breast cancer recurrence and mortality. Recently, large international trials evaluating extended endocrine therapy as well as ovarian suppression with and without tamoxifen or exemestane have been reported. These studies add to the large body of existing data related to adjuvant endocrine therapy in premenopausal women with breast cancer and provide additional therapeutic options in those at high risk of disease recurrence. This review will synthesize the most recent data and provide an evidenced based approach, highlighting quality-of-life concerns, when considering adjuvant endocrine therapies in premenopausal women.

    Superficial transitional cell carcinoma represents 50 to 80% of newly diagnosed bladder cancer in various countries. Transurethral resection of the urinary bladder is the standard procedure for biopsy and treatment superficial bladder cancer. However recurrence tumors after transurethral resection alone is high enough (50-90%). Intravesical chemotherapy for prophylaxis after complete transurethral resection is reducing recurrence rate about 1 5%. Adjuvant intravesical Bacillus of Calmette and Guerin (BCG) is reducing recurrence rate about 30%, but frequency side effects of this therapy is very high. Purpose of this study is appreciate efficacy adjuvant PDT with photosensitizer Photogeme (Russia) of superficial bladder cancer for prophylaxis after complete transurethral resection. The follow up was from 3 to 63 months (27 months, on average). Sixty-five patients (75.6%) showed no recurrence. For the follow up period, the recurrence was revealed in 21 (24.4%) patient, in two of them it was progressing (one case of invasive growth and one case of remote metastases). Four cases of recurrence were revealed 4 months after the surgery. In other cases, the recurrence was diagnosed from 9 to 18 months.

    Phytotherapeutic pharmaceuticals and herbal medicinal products with its roots in classical phytotherapeutic medicine have a well-established role in otolaryngological therapy, especially for diseases of the upper airways and acute and chronic infections. A thorough selection and application could mean huge benefit for the patient, in particular in cases with contraindications, chemo- and antibiotic resistance or patient request. Besides, it might spare other medications. Phytotherapeutic pharmaceuticals must fulfil the same criteria of quality, effectiveness and harmlessness of evidence-based medicine like chemical pharmaceuticals, although they are often prescribed due to its well established or traditional based use. This review focuses on phytotherapeutic therapies well established within the European Community for otolaryngologic disease patterns by referring to clinical studies or meta-analysis.

    Better compliance and persistence with therapy are associated with improved patient outcomes. As more and more patients survive breast cancer, compliance with adjuvant therapy becomes increasingly important. In clinical trials, compliance with adjuvant endocrine therapy among women with breast cancer is usually high. Retrospective analyses of databases and medical records from clinical practice, insurance databases of prescription refills, and survey data show a significant decrease in persistence after 12 months of therapy. With ongoing therapy, a further decline in persistence of up to 50% has been reported. A consistent methodology is needed to measure patient behavior and identify patients who are not adhering to therapy. Promising strategies for enhancing adherence to treatment in clinical practice include improving access to health care, increasing patient satisfaction, managing side effects, patient education, and better communication between the patient and health care provider. Positive relationships between patients and their health care providers, and frequent monitoring and feedback, may be most effective. While the lack of conformity across studies in measuring makes cross-study comparisons difficult, this review evaluates the available data regarding compliance and persistence with adjuvant endocrine therapies for breast cancer (tamoxifen and aromatase inhibitors) and presents strategies for improving adherence.

    Purpose: Intrahepatic cholangiocarcinomas (IHC) are rare tumors for which large randomized studies regarding the use of radiation are not available. The purpose of this study was to examine the role of adjuvant and definitive radiation therapy in the treatment of IHC in a large group of patients. Methods and Materials: This is a retrospective analysis of 3,839 patients with IHC collected from the Surveillance, Epidemiology, and End Results (SEER) database. The primary endpoint was overall survival (OS). Results: Patients received either surgery alone (25%), radiation therapy alone (10%), surgery and adjuvant radiation therapy (7%) or no treatment (58%). The median age of the patient population was 73 years (range, 22-102 years); 52% of patients were male and 81% were Caucasian. Median OS was 11 (95% confidence interval [CI], 9-13), 6 (95% CI, 5-6), 7 (95% CI, 6-8), and 3 months for surgery and adjuvant radiation therapy, sugery alone, radiation therapy alone, and no treatment, respectively. The OS was significantly different between surgery alone and surgery and adjuvant radiation therapy (p = 0.014) and radiation therapy alone and no treatment (p < 0.0001). Use of surgery and adjuvant radiation therapy conferred the greatest benefit on OS (HR = 0.40; 95% CI, 0.34-0.47), followed by surgery alone (hazard ratio [HR], 0.49; 95% CI, 0.44-0.54) and radiation therapy alone (HR, 0.68; 95% CI, 0.59-0.77) compared with no treatment, on multivariate analysis. Propensity score adjusted hazard ratios (controlling for age, race/ethnicity, stage, and year of diagnosis) were also significant (surgery and adjuvant radiation therapy vs. surgery alone (HR, 0.82; 95% CI, 0.70-0.96); radiation therapy alone vs. no treatment (HR, 0.67; 95% CI, 0.58-0.76)). Conclusions: The study results suggest that adjuvant and definitive radiation treatment prolong survival, although cure rates remain low. Future studies should evaluate the addition of chemotherapy and biologics to the treatment of

    Purpose: To describe the anatomic distribution of regionally recurrent disease in patients with stage III melanoma in the axilla after curative-intent surgery with and without adjuvant radiation therapy. Methods and Materials: A single-institution, retrospective analysis of a prospective database of 277 patients undergoing curative-intent treatment for stage III melanoma in the axilla between 1992 and 2012 was completed. For patients who received radiation therapy and those who did not, patterns of regional recurrence were analyzed, and univariate analyses were performed to assess for potential factors associated with location of recurrence. Results: There were 121 patients who received adjuvant radiation therapy because their clinicopathologic features conferred a greater risk of regional recurrence. There were 156 patients who received no radiation therapy. The overall axillary control rate was 87%. There were 37 patients with regional recurrence; 17 patients had received adjuvant radiation therapy (14%), and 20 patients (13%) had not. The likelihood of in-field nodal recurrence was significantly less in the adjuvant radiation therapy group (P=.01) and significantly greater in sites adjacent to the axilla (P=.02). Patients with high-risk clinicopathologic features who did not receive adjuvant radiation therapy also tended to experience in-field failure rather than adjacent-field failure. Conclusions: Patients who received adjuvant radiation therapy were more likely to experience recurrence in the adjacent-field regions rather than in the in-field regions. This may not simply reflect higher-risk pathology. Using this data, it may be possible to improve outcomes by reducing the number of adjacent-field recurrences after adjuvant radiation therapy.

    Summary Introduction This phase II trial investigated chemoradiation followed by surgery and 2 years of adjuvant tetrathiomolybdate (TM) for resectable esophageal cancer. Methods Patients with resectable, locally advanced esophageal cancer received neoadjuvant cisplatin 60 mg/m2 (days 1 and 22), paclitaxel 60 mg/m2 (days 1, 8, 15, and 22), and 45 Gy hyperfractionated radiotherapy for 3 weeks followed by transhiatal esophagectomy. TM 20 mg PO QD was started 4 weeks post-op, and continued for 2 years to maintain the ceruloplasmin level between 5 and 15 mg/dl. Results Sixty-nine patients were enrolled (median age, 60 years). Sixty-six patients underwent surgery and 61 patients had a complete resection. Histologic complete response rate was 10 %. Twenty-one patients did not receive TM (metastases noted in the peri-operative period, prolonged post-operative recovery time, or patient refusal). Forty-eight patients started TM; 14 completed 24 months of treatment, 11 completed 10–18 months, 15 completed 2–8 months, and 8 completed ≤1 month. Twenty-seven patients had disease recurrence. With a median follow-up of 55 months, 25 patients were alive without disease, 1 was alive with disease, and 43 have died. Three-year recurrence-free survival was 44 % (95 % CI, 32–55 %) and the three-year overall survival was 45 % (95 % CI 33–56 %). Conclusions TM is an antiangiogenic agent that is well tolerated in the adjuvant setting. Disease-free survival and overall survival are promising when compared to historical controls treated at our institution with a similar regimen that did not include TM. However, the challenges associated with prolonged administration limit further investigation. PMID:22847786

    Hormone receptor (HR) positive breast cancers represent the vast majority of breast cancers. Adjuvant and/or neoadjuvant endocrine therapy is highly effective and appropriate for nearly all women with HR positive tumors. Adjuvant tamoxifen (TAM) is a major endocrine treatment option, which has been found to be effective in both premenopausal and postmenopausal patients. Considerable evidence has been accrued of a benefit for ovarian ablation or suppression (OA/S) in premenopausal patients, for aromatase inhibitors (AIS) in postmenopausal patients, for the longer duration of adjuvant endocrine therapy and for the clinical utility of neoadjuvant endocrine therapy. Clinical practice guidelines should keep changing with developing evidence-based practice guidelines pertaining to breast cancer care. The present publication conducted a comprehensive systematic review of the literature addressing the use of endocrine therapy as adjuvant or neoadjuvant therapy for HR positive breast cancer, focusing on selecting the best agents for both premenopausal and postmenopausal patients, as well as the optimal duration of such treatment.

    Purpose: Prolonged radiation therapy treatment time (RTT) is associated with worse survival in several tumor types. This study investigated whether delays during adjuvant radiation therapy impact overall survival (OS) in gastric cancer. Methods and Materials: The National Cancer Data Base was queried for patients with resected gastric cancer who received adjuvant radiation therapy with National Comprehensive Cancer Network–recommended doses (45 or 50.4 Gy) between 1998 and 2006. RTT was classified as standard (45 Gy: 33-36 days, 50.4 Gy: 38-41 days) or prolonged (45 Gy: >36 days, 50.4 Gy: >41 days). Cox proportional hazards models evaluated the association between the following factors and OS: RTT, interval from surgery to radiation therapy initiation, interval from surgery to radiation therapy completion, radiation therapy dose, demographic/pathologic and operative factors, and other elements of adjuvant multimodality therapy. Results: Of 1591 patients, RTT was delayed in 732 (46%). Factors associated with prolonged RTT were non-private health insurance (OR 1.3, P=.005) and treatment at non-academic facilities (OR 1.2, P=.045). Median OS and 5-year actuarial survival were significantly worse in patients with prolonged RTT compared with standard RTT (36 vs 51 months, P=.001; 39 vs 47%, P=.005); OS worsened with each cumulative week of delay (P<.0004). On multivariable analysis, prolonged RTT was associated with inferior OS (hazard ratio 1.2, P=.002); the intervals from surgery to radiation therapy initiation or completion were not. Prolonged RTT was particularly detrimental in patients with node positivity, inadequate nodal staging (<15 nodes examined), and those undergoing a cycle of chemotherapy before chemoradiation therapy. Conclusions: Delays during adjuvant radiation therapy appear to negatively impact survival in gastric cancer. Efforts to minimize cumulative interruptions to <7 days should be considered.

    Anti-angiogenic therapies have demonstrated their value in the setting of advanced cancer, and are being explored for use in micrometastatic disease. Recent preclinical studies suggest that adjuvant anti-vascular endothelial growth factor (VEGF) therapies may increase the risk of metastasis.

    OBJECTIVES We investigated the development of binding and neutralizing antibodies to GM-CSF in patients receiving prolonged therapy with GM-CSF as adjuvant therapy of melanoma and the impact of these antibodies on biologic effects. METHODS Fifty-three patients with high-risk melanoma which had been surgically excised were treated with GM-CSF, 125 µg/m2 daily for 14 days every 28 days for 1 year following surgical resection of disease. Serum samples for antibodies to GM-CSF were measured before treatment and on Study Days 155 and 351. Blood draws for testing biologic effects were keyed to GM-CSF administration: Days 0 (before), 15 (after 14 days on GM-CSF), 29 (after 14 days off GM-CSF), 155, and 351 (after 14 days on GM-CSF in the 6th and 13th cycle of treatment). RESULTS Of 53 patients enrolled, 43 were evaluable for the development of anti-GM-CSF antibodies. Of these, 93% developed binding antibodies and 42% developed both binding and neutralizing antibodies. The increase in the white blood cell (WBC) count, percent eosinophils, or neopterin levels engendered by GM-CSF administration, was abrogated or markedly decreased in patients with neutralizing antibodies but not in patients who developed only binding antibodies. CONCLUSIONS Ninety-three percent of patients with melanoma treated with GM-CSF as adjuvant therapy develop antibodies to GM-CSF. In those with neutralizing antibodies, a diminution of the biologic effects of GM-CSF was observed. The development of neutralizing antibodies might also abrogate the potential clinical benefit of this treatment and should be considered in the design of future clinical trials. PMID:25286079

    Several authors found that the prognosis of overweight and obese breast cancer (BC) patients was lower than that of normal weight patients. We present the first study which evaluates the impact of body mass index (BMI) on compliance (i.e. to start a recommended therapy) and persistence to adjuvant BC therapy. An unselected cohort of 766 patients (≤75 years) diagnosed from 1997 to 2009 was analyzed in relevance to the four adjuvant therapy modalities: (A) radiation, (B) chemotherapy, (C) therapy with trastuzumab, and (D) endocrine therapy. With respect to compliance, multivariate analyses calculated Odds ratios (ORs) >1 for increased BMI in all four therapy modalities, i.e. increased BMI had a positive influence on compliance. The results were significant for radiotherapy (OR,2.37;95%CI,1.45-3.88;p < 0.001) and endocrine therapy (OR,1.92;95%CI,1.21-3.04;p = 0.002) and showed a trend in chemotherapy (OR,1.42;95%CI,0.97-2.08;p = 0.063). Analyzing persistence, increasing BMI had ORs <1 for chemotherapy and therapy with trastuzumab, both not reaching statistical significance. For endocrine therapy, increasing BMI was a significant predictor for persistence (OR,1.35;95%CI,1.08-1.80;p = 0.042). Failure of compliance and persistence to adjuvant therapy does not pose a contributing factor for the observed unfavorable prognosis in overweight/obese BC patients. In most therapy modes, patients with increasing BMI demonstrated a higher motivation and perseverance to the recommended treatment.

    Altered glycosylation is a predominant feature of tumour cells; it serves for cell adhesion and detachment, respectively, and facilitates the immune escape of these cells. Therefore changes in the expression of glycosyltransferase genes could help to identify circulating tumour cells (CTCs) in the blood samples of cancer patients using a quantitative polymerase chain reaction (PCR) approach. Blood samples of healthy donors were inoculated with certain numbers of established breast cancer cell line cells, thus creating a model system. These samples were analysed by quantitative PCR for the expression of six different glycosyltransferase genes. The three genes with the best results in the model system were consecutively applied to samples from adjuvant breast cancer patients and of healthy donors. FUT3 and GALNT6 showed the highest increase in relative expression, while GALNT6 and ST3GAL3 were the first to reach statistically significant different ∆CT-values comparing the sample with and without addition of tumour cells. These three genes were applied to patient samples, but did not show any significant results that may suggest the presence of CTCs in the blood. Although the relative expression of some of the glycosyltransferase genes exhibited reasonable results in the model system, their application to breast cancer patient samples will have to be further improved, e.g. by co-analysis of patient blood samples by gold-standard methods.

    Objective Chordomas are locally aggressive, highly recurrent tumors requiring adjuvant radiotherapy following resection for successful management. We retrospectively reviewed patients treated for intracranial chordomas with adjuvant stereotactic radiosurgery (SRS) and stereotactic radiation therapy (SRT). Methods A total of 57 patients underwent 83 treatments at the UCLA Medical Center between February 1990 and August 2011. Mean follow-up was 57.8 months. Mean tumor diameter was 3.36 cm. Overall, 8 and 34 patients received adjuvant SRS and SRT, and the mean maximal dose of radiation therapy was 1783.3 cGy and 6339 cGy, respectively. Results Overall rate of recurrence was 51.8%, and 1- and 5-year progression-free survival (PFS) was 88.2% and 35.2%, respectively. Gross total resection was achieved in 30.9% of patients. Adjuvant radiotherapy improved outcomes following subtotal resection (5-year PFS 62.5% versus 20.1%; p = 0.036). SRS and SRT produced comparable rates of tumor control (p = 0.28). Higher dose SRT (> 6,000 cGy) (p = 0.013) and younger age (< 45 years) (p = 0.03) was associated with improved rates of tumor control. Conclusion Adjuvant radiotherapy is critical following subtotal resection of intracranial chordomas. Adjuvant SRT and SRS were safe and improved PFS following subtotal resection. Higher total doses of SRT and younger patient age were associated with improved rates of tumor control. PMID:26949587

    The disruption of self-tolerance against neuroblastoma is the ultimate goal of an effective DNA-vaccine. We demonstrate the induction of protective immunity against syngeneic murine NXS2 neuroblastoma in A/J mice following vaccination with tyrosine hydroxylase (TH)-derived antigens. Oral gene delivery was accomplished using an attenuated strain of Salmonella typhimurium as a carrier harboring vectors encoding for mouse tyrosine hydroxylase (mTH) antigens. Vaccination was effective in protecting animals from a lethal challenge with wild-type NXS2 tumor cells. These findings were extended by comparing efficacy of mTH minigene vaccines with a minigene vaccine comprising three novel epitopes isolated fom NXS2 neuroblastoma cells. For this purpose, MHC class I was immunoprecipitated from NXS2 cell lysates, and peptides were eluted and examined in tandem-mass spectrometry analysis. This led to the identification of three novel natural MHC class I peptide ligands: TEALPVKLI, from ribonucleotide reductase M2; NEYIMSLI, from Ser/Thr protein phosphatase 2A; and FEMVSTLI, of unknown origin. Two minigenes were constructed, one encoding for the three novel epitopes and the second for three known mTH-derived epitopes with high predicted binding affinity to MHC class I, by cloning them into the mammalian expression vector pCMV-3FUB. Immunized mice showed a reduction in primary tumor growth and the absence of spontaneous liver metastasis in the majority of animals. Importantly, there was no significant difference between the two minigenes, suggesting that, compared with tumor peptide isolation, mTH epitope prediction is similarly effective for designing efficient DNA-minigene vaccines. In summary, these findings establish proof of the concept that disruption of self-tolerance against neuroblastoma-associated epitopes may be an effective adjuvant therapeutic strategy.

    In resected pancreas cancer, adjuvant therapy improves outcomes and is considered the standard of care for patients who recover sufficiently post operatively. Chemotherapy or combined chemotherapy and radiation therapy (chemoradiation; CRT) are strategies used in the adjuvant setting. However, there is a lack of evidence to suggest whether the addition of RT to chemotherapy translates to an improvement in clinical outcomes. This is true even when accounting for the subset of patients with a higher risk for recurrence, such as those with R1 and lymph node positive disease. When considering the direct and indirect costs, impact on quality of life and questionable added clinical benefit, the true “net health benefit” from added RT to chemotherapy becomes more uncertain. Future directions, including the utilization of modern RT, integration of novel therapies, and intensifying chemotherapy regimens may improve outcomes in resected pancreas cancer. PMID:26620819

    Liver transplantation (LT) for hepatocellular carcinoma (HCC) within Milan criteria is a widely accepted optimal therapy. Neo-adjuvant therapy before transplantation has been used as a bridging therapy to prevent dropout during the waiting period and as a down-staging method for the patient with intermediate HCC to qualify for liver transplantation. Transarterial chemoembolization and radiofrequency ablation are the most commonly used method for locoregional therapy. The data associated with newer modalities including drug-eluting beads, radioembolization with Y90, stereotactic radiation therapy and sorafenib will be discussed as a tool for converting advanced HCC to LT candidates. The concept "ablate and wait" has gained the popularity where mandated observation period after neo-adjuvant therapy allows for tumor biology to become apparent, thus has been recommended after down-staging. The role of neo-adjuvant therapy with conjunction of "ablate and wait" in living donor liver transplantation for intermediate stage HCC is also discussed in the paper. PMID:24833861

    Purpose: Despite results of randomized trials that support adjuvant radiation therapy (RT) after radical prostatectomy (RP) for prostate cancer with adverse pathologic features (APF), many clinicians favor selective use of salvage RT. This survey was conducted to evaluate the beliefs and practices of radiation oncologists (RO) and urologists (U) regarding RT after RP. Methods and Materials: We designed a Web-based survey of post-RP RT beliefs and policies. Survey invitations were e-mailed to a list of 926 RO and 591 U. APF were defined as extracapsular extension, seminal vesicle invasion, or positive surgical margin. Differences between U and RO in adjuvant RT recommendations were evaluated by comparative statistics. Multivariate analyses were performed to evaluate factors predictive of adjuvant RT recommendation. Results: Analyzable surveys were completed by 218 RO and 92 U (overallresponse rate, 20%). Adjuvant RT was recommended based on APF by 68% of respondents (78% RO, 44% U, p <0.001). U were less likely than RO to agree that adjuvant RT improves survival and/or biochemical control (p < 0.0001). PSA thresholds for salvage RT were higher among U than RO (p < 0.001). Predicted rates of erectile dysfunction due to RT were higher among U than RO (p <0.001). On multivariate analysis, respondent specialty was the only predictor of adjuvant RT recommendations. Conclusions: U are less likely than RO to recommend adjuvant RT. Future research efforts should focus on defining the toxicities of post-RP RT and on identifying the subgroups of patients who will benefit from adjuvant vs. selective salvage RT.

    Adjuvant systemic therapy along with screening has been key to the observed improvements in disease-free and overall survival (DFS/OS) in breast cancer. Improvements in overall survival already take into account therapy related toxicities that can result in death. However, this measure alone does not adequately capture the impact on health-related quality of life. Therefore, it is important to examine the prevalence, frequency and short/long-term impact of therapy-related toxicities, identify patients who might be at greatest risk. Ultimately decisions regarding expected therapy benefits (relative and absolute percentage improvements in DFS/OS) must be made against a background of known potential harms. For many patients with early breast cancer (EBC), their risk of recurrence is not zero but is small. At the same time, for many therapies for early stage breast cancer, the risk of serious side effects is small but is not zero. As we better understand the long-term side effects of adjuvant chemotherapy and targeted therapy, it becomes critical to integrate our growing understanding of breast cancer biology with standard high-quality histopathologic measures to better identify the patients most likely to benefit from the various options for combined multimodality therapy. Hence, we must strive against the notion of recommending adjuvant systemic chemotherapy "just in case."

    There is a paucity of literature systemically examining the effects of access to cancer care resources on adjuvant endocrine therapy (AET) use behaviors, especially in underserved regions such as the Appalachian region in the United States, where gaps in healthcare access are well documented. The objectives of this study were to explore AET adherence and persistence in Appalachia, delineate the effects of access to care cancer on adherence/persistence, and evaluate the influences of adherence and persistence on overall survival.A retrospective cohort study from 2006 to 2008 was conducted among female breast cancer survivors living in the Appalachian counties of 4 states (PA, OH, KY, and NC). We linked cancer registries to Medicare claims data and included patients with invasive, nonmetastatic, hormone-receptor-positive breast cancer who received guideline-recommended AET. Medication adherence was defined as corresponding to a Medication Possession Ratio (MPR) ≥0.8 and logistic regression was utilized to assess predictors of adherence. Medication nonpersistence was defined as the discontinuation of drugs after exceeding a 60-day medication gap, and multivariate adjusted estimates of nonpersistence were obtained using the Cox proportional hazards (PH) model.About 31% of the total 428 patients were not adherent to AET, and 30% were not persistent over an average follow-up period of 421 days. Tamoxifen, relative to aromatase inhibitors, was associated with higher odds of adherence (odds ratio = 2.82, P < 0.001) and a lower risk of nonpersistence (hazard ratio = 0.40, P < 0.001). Drug-related side effects like pain may be an important factor leading to nonadherence and early discontinuation. In addition, aromatase inhibitor (AI) adherence and persistence were significantly influenced by out-of-pocket drug costs, dual eligibility status, and coverage gaps. Nonadherence to and nonpersistence with AET were associated with higher risks of all-cause mortality.Our findings

    Purpose The purpose of this study is to assess the role of adjuvant therapy in stage I-III gallbladder cancer (GBC) patients who have undergone R0 resection. Materials and Methods Clinical data were collected on 441 consecutive patients who underwent R0 resection for stage I-III GBC. Eligible patients were classified into adjuvant therapy and surveillance only groups. Propensity score matching (PSM) between the two groups was performed, adjusting clinical factors. Results In total, 84 and 279 patients treated with adjuvant therapy and followed up with surveillance only, respectively, were included in the analysis. Before PSM, the 5-year relapse-free survival (RFS) rate was lower in the adjuvant therapy group than in the surveillance only group (50.8% vs. 74.8%, p < 0.001), although there was no statistically significant difference in the 5-year overall survival (OS) rate (66.2% vs. 79.5%, p=0.089). After the PSM, baseline characteristics became comparable and there were no differences in the 5-year RFS (50.8% vs. 64.8%, p=0.319) and OS (66.2% vs. 70.4%, p=0.703) rates between the two groups. Conclusion The results suggest that fluoropyrimidine-based adjuvant therapy is not indicated in stage I-III GBC patients who have undergone R0 resection. PMID:26875193

    Background: Peritumoral vascular invasion (PVI) may assist in assigning optimal adjuvant systemic therapy for women with early breast cancer. Patients and methods: Patients participated in two International Breast Cancer Study Group randomized trials testing chemoendocrine adjuvant therapies in premenopausal (trial VIII) or postmenopausal (trial IX) node-negative breast cancer. PVI was assessed by institutional pathologists and/or central review on hematoxylin–eosin-stained slides in 99% of patients (analysis cohort 2754 patients, median follow-up >9 years). Results: PVI, present in 23% of the tumors, was associated with higher grade tumors and larger tumor size (trial IX only). Presence of PVI increased locoregional and distant recurrence and was significantly associated with poorer disease-free survival. The adverse prognostic impact of PVI in trial VIII was limited to premenopausal patients with endocrine-responsive tumors randomized to therapies not containing goserelin, and conversely the beneficial effect of goserelin was limited to patients whose tumors showed PVI. In trial IX, all patients received tamoxifen: the adverse prognostic impact of PVI was limited to patients with receptor-negative tumors regardless of chemotherapy. Conclusion: Adequate endocrine adjuvant therapy appears to abrogate the adverse impact of PVI in node-negative disease, while PVI may identify patients who will benefit particularly from adjuvant therapy.

    Aromatase inhibitors are superior to tamoxifen as adjuvant therapy in postmenopausal patients with hormone-responsive breast cancer. We report the follow-up efficacy results from the N-SAS BC 03 trial (UMIN CTRID: C000000056) where anastrozole was compared with tamoxifen as adjuvant therapy in postmenopausal Japanese patients with hormone-responsive early breast cancer. The full analysis set contained 696 patients (anastrozole arm, n = 345; tamoxifen arm, n = 351). The log-rank test was used to compare the two groups in terms of disease-free survival (DFS) and relapse-free survival (RFS); Kaplan-Meier estimates were calculated. The treatment effects were estimated by Cox's proportional hazards model. To examine time-varying effect of hazard ratios, we estimated time-varying hazard ratios at time t [HR(t)] using data from time t up to 12 months. After a median follow-up of 98.5 months, hazard ratios (95% CIs) were 0.90 (0.65-1.24; log-rank p = 0.526) for DFS and 0.83 (0.56-1.23; log-rank p = 0.344) for RFS. Hazard ratios (95% CIs) for DFS and RFS up to 36 months were 0.69 (0.40-1.17) and 0.54 (0.27-1.06) and those after 36 months were 1.06 (0.70-1.59) and 1.05 (0.64-1.73), respectively. Time-varying hazard ratios for both DFS and RFS showed that hazard ratios were initially in favor of anastrozole and approached 1.0 at around 36 months. Superior efficacy of anastrozole to tamoxifen suggested by the initial analysis was not confirmed in the present analysis after a long-term follow-up period. Advantage of anastrozole was the greatest immediately after switching from tamoxifen and then decreased thereafter.

    AIM: To evaluate the long-term results of conventional chemoradiotherapy and laparoscopic mesorectal excision in rectal adenocarcinoma patients without adjuvant therapy. METHODS: Patients with biopsy-proven adenocarcinoma of the rectum staged cT3-T4 by endoscopic ultrasound or magnetic resonance imaging received neoadjuvant continuous infusion of 5-fluorouracil for five weeks and concomitant radiotherapy. Laparoscopic surgery was planned after 5-8 wk. Patients diagnosed with ypT0N0 stage cancer were not treated with adjuvant therapy according to the protocol. Patients with ypT1-2N0 or ypT3-4 or N+ were offered 5-fluorouracil-based adjuvant treatment on an individual basis. An external cohort was used as a reference for the findings. RESULTS: One hundred and seventy six patients were treated with induction chemoradiotherapy and 170 underwent total mesorectal excision. Cancer staging of ypT0N0 was achieved in 26/170 (15.3%) patients. After a median follow-up of 58.3 mo, patients with ypT0N0 had five-year disease-free and overall survival rates of 96% (95%CI: 77-99) and 100%, respectively. We provide evidence about the natural history of patients with localized rectal cancer achieving a complete response after preoperative chemoradiation. The inherent good prognosis of these patients will have implications for clinical trial design and care of patients. CONCLUSION: Withholding adjuvant chemotherapy after complete response following standard neoadjuvant chemoradiotherapy and laparoscopic mesorectal excision might be safe within an experienced multidisciplinary team.

    To investigate the increase in MRI contrast enhancement (CE) occurring in glioblastoma during the period between surgery and initiation of chemo-radiotherapy, thirty-seven patients with newly diagnosed glioblastoma were analyzed by early post-operative magnetic resonance (EPMR) imaging within three days of surgery and by pre-adjuvant magnetic resonance (PAMR) examination before adjuvant therapy. Areas of new CE were investigated by use of EPMR diffusion-weighted imaging and PAMR perfusion imaging (by arterial spin-labeling). PAMR was acquired, on average, 29.9 days later than EPMR (range 20-37 days). During this period an increased area of CE was observed for 17/37 patients. For 3/17 patients these regions were confined to areas of reduced EPMR diffusion, suggesting postsurgical infarct. For the other 14/17 patients, these areas suggested progression. For 11/17 patients the co-occurrence of hyperperfusion in PAMR perfusion suggested progression. PAMR perfusion and EPMR diffusion did not give consistent results for 3/17 patients for whom small new areas of CE were observed, presumably because of the poor spatial resolution of perfusion imaging. Before initiation of adjuvant therapy, areas of new CE of resected glioblastomas are frequently observed. Most of these suggest tumor progression, according to EPMR diffusion and PAMR perfusion criteria. PMID:23264191

    Melanoma incidence and mortality rates are rising in Italy, indicating that more effective treatments are required both in the adjuvant and metastatic settings. We analyzed clinical practices in the adjuvant and metastatic settings by conducting a nationwide survey of clinicians responsible for managing melanoma treatment and follow-up in a representative sample of Italian hospitals. 95% of participating hospitals completed the panel of questions on adjuvant and metastatic treatment, making it likely that these results give a realistic picture of treatment and follow-up of melanoma patients in Italy. In low-volume hospitals (<25 new melanoma diagnoses yearly) adjuvant therapy was significantly more used than in large-volume hospitals for patients in stage III and IV (82 versus 66% and 56 versus 30%, respectively), and only 11% of patients were enrolled in clinical trials. In the metastatic setting dacarbazine was the preferred first-line treatment (32%) followed by polychemotherapy (23%); 12% of patients were enrolled in clinical trials and less than 10% received interleukin-2, usually subcutaneously. The information provided by this study was used by the Italian Melanoma Intergroup to improve the quality of care and to redirect financial resources. PMID:23736267

    Purpose To evaluate the benefit of adjuvant radiation therapy (RT) for retroperitoneal liposarcoma (RPLS) following gross tumor removal. Materials and Methods We reviewed 77 patients with primary RPLS surgically treated between January 2000 and December 2013. Cases with gross residual disease were excluded. Tumor grade was evaluated according to the French Federation of Cancer Centers Sarcoma Group (FNCLCC) system. Adjuvant RT was delivered to 32 patients (42%) using external beam RT alone. Median follow-up time was 36 months (range, 5 to 169). Results Among 77 patients, 33 (43%) presented with well-differentiated, 31 (40%) with de-differentiated, 8 (10%) with myxoid/round and 4 (5%) with pleomorphic morphology. The RT group included less well-differentiated subtype than surgery group (28% vs. 53%). During follow up, 34 patients (44%) showed local recurrence. Local recurrence rate was lower in the RT group (38%) compared to the surgery group (49%). The 3-year local control rate (LC) was 55.6%, and the 3-year overall survival (OS) was 82.1%. Tumor histology and FNCLCC grade were significantly associated with local recurrence. There was no statistical significance of adding adjuvant RT in LC (p = 0.312). However, patients with tumor histology other than well-differentiated subtype showed marginally decreased local recurrence rate after adjuvant RT (3-year LC, RT 43.9% vs. no RT 35.3%; p = 0.087). Conclusion RPLS patients receiving RT experienced less local recurrence. We suggest that the addition of adjuvant RT may be related to improvement of LCs, especially in patients with non-favorable histologic subtypes. PMID:27730802

  10. Oncologist use of the Adjuvant! model for risk communication: a pilot study examining patient knowledge of 10-year prognosis

    PubMed Central

    2009-01-01

    Background Our purpose was to collect preliminary data on newly diagnosed breast cancer patient knowledge of prognosis before and after oncology visits. Many oncologists use a validated prognostic software model, Adjuvant!, to estimate 10-year recurrence and mortality outcomes for breast cancer local and adjuvant therapy. Some oncologists are printing Adjuvant! screens to use as visual aids during consultations. No study has reported how such use of Adjuvant! printouts affects patient knowledge of prognosis. We hypothesized that Adjuvant! printouts would be associated with significant changes in the proportion of patients with accurate understanding of local therapy prognosis. Methods We recruited a convenience sample of 20 patients seen by 2 senior oncologists using Adjuvant! printouts of recurrence and mortality screens in our academic medical center. We asked patients for their estimates of local therapy recurrence and mortality risks and counted the number of patients whose estimates were within ± 5% of Adjuvant! before and after the oncology visit, testing whether pre/post changes were significant using McNemar's two-sided test at a significance level of 5%. Results Two patients (10%) accurately estimated local therapy recurrence and mortality risks before the oncology visit, while seven out of twenty (35%) were accurate afterwards (p = 0.125). Conclusion A majority of patients in our sample were inaccurate in estimating their local therapy recurrence and mortality risks, even after being shown printouts summarizing these risks during their oncology visits. Larger studies are needed to replicate or repudiate these preliminary findings, and test alternative methods of presenting risk estimates. Meanwhile, oncologists should be wary of relying exclusively on Adjuvant! printouts to communicate local therapy recurrence and mortality estimates to patients, as they may leave a majority of patients misinformed.

    Extended use of antimycotics in oral candidiasis therapy gives rise to problems related to fungal drug resistance. The aim of this pilot study was to investigate the efficacy of tissue tolerable plasma (TTP) in denture stomatitis patients. It was hypothesised that (I): erythema and (IIa): complaint remission would be accelerated and (IIb): colony forming unit (CFU) reduction would be improved. The halves of the upper jaws of eight patients were randomly assigned to control (nystatin, chlorhexidine and placebo treatment) and test sides (nystatin, chlorhexidine and TTP administered six times each 7 days). The patients and the investigators, who were different from the therapists, were both blinded. Compared to the control sides, the erythema surface was reduced significantly more extensively on the test sides between 2 and 6 weeks of antifungal therapy (P ≤ 0.05). Visual analogue scale values and the frequency of moderate or heavy growth of Candida post-treatment did not differ significantly between both sides (P > 0.05). The primary hypothesis was confirmed, which may be interpreted as an accelerated remission. As drug therapy is usually limited to the time in which signs of infection are present, TTP might help reducing antifungal use. Even though the secondary hypotheses were not confirmed, persistence of Candida might be only colonisation.

    Multiple strategies for endocrine treatment of premenopausal women with hormone-responsive breast cancer have been assessed and results have been presented over the last two years. These include tamoxifen for 5-10 years (ATLAS and aTTom), tamoxifen for 5 years followed by aromatase inhibitor (AI) for 5 years for women who have become postmenopausal (MA-17); ovarian ablation (OA) by surgery (EBCTCG overview); ovarian function suppression (OFS) by LHRH agonist (LHRH agonist meta-analysis); or combinations of approaches including OFS plus tamoxifen or AI (SOFT, TEXT, ABCSG 12 and E3193). Many of these trials have taken place in the backdrop of (neo)adjuvant chemotherapy which can confound interpretation because such therapy can suppress ovarian function either transiently or permanently. Nonetheless these trials suggest in aggregate that 10 years of tamoxifen are better than 5 years and that a program of extended adjuvant therapy of tamoxifen for 5 years followed by aromatase inhibitor for 5 years is effective for suitable candidates. The SOFT and E3193 trials do not show a major advantage for use of OFS + tamoxifen compared to tamoxifen alone. The joint SOFT/TEXT analysis and ABCGS12 trials both suggest that outcomes can be excellent with the use of combined endocrine therapy alone in properly selected patients but give conflicting results with regard to potential benefits for OFS + AI compared with OFS + tamoxifen. Further work will be needed to ascertain long-term outcomes, identify factors that predict who will benefit from extended adjuvant endocrine therapy, and assess role of OFS by medical or surgical means. It is clear, however, that endocrine therapy is a critical part of the adjuvant regimen for most premenopausal women with hormone-responsive breast cancer, and a subset of these women with luminal A-type tumors can be safely treated with endocrine therapy alone.

    Current adjuvant treatment modalities for breast cancer that express the estrogen receptor or progesterone receptor include adjuvant anti-estrogen therapies, and tamoxifen and aromatase inhibitors. Bone, including the jaw, is an endocrine-sensitive organ, as are other oral structures. This review examines the potential links between adjuvant anti-estrogen treatments in postmenopausal women with hormone receptor positive breast cancer and oral health. A search of PubMed, EMBASE, CENTRAL, and the Web of Knowledge was conducted using combinations of key terms “breast,” “cancer,” “neoplasm,” “Tamoxifen,” “Aromatase Inhibitor,” “chemotherapy,” “hormone therapy,” “alveolar bone loss,” “postmenopausal bone loss,” “estrogen,” “SERM,” “hormone replacement therapy,” and “quality of life.” We selected articles published in peer-reviewed journals in the English. The authors found no studies reporting on periodontal diseases, alveolar bone loss, oral health, or oral health-related quality of life in association with anti-estrogen breast cancer treatments in postmenopausal women. Periodontal diseases, alveolar bone density, tooth loss, and conditions of the soft tissues of the mouth have all been associated with menopausal status supporting the hypothesis that the soft tissues and bone of the oral cavity could be negatively affected by anti-estrogen therapy. As a conclusion, the impact of adjuvant endocrine breast cancer therapy on the oral health of postmenopausal women is undefined. The structures of the oral cavity are influenced by estrogen; therefore, anti-estrogen therapies may carry the risk of oral toxicities. Oral health care for breast cancer patients is an important but understudied aspect of cancer survivorship. PMID:22986813

    BACKGROUND Adherence to adjuvant endocrine therapy (AET) for estrogen receptor-positive breast cancer remains suboptimal, which suggests that women are not getting the full benefit of the treatment to reduce breast cancer recurrence and mortality. The majority of studies on adherence to AET focus on identifying factors among those women at the highest levels of adherence and provide little insight on factors that influence medication use across the distribution of adherence. OBJECTIVE To understand how factors influence adherence among women across low and high levels of adherence. METHODS A retrospective evaluation was conducted using the Truven Health MarketScan Commercial Claims and Encounters Database from 2007–2011. Privately insured women aged 18-64 years who were recently diagnosed and treated for breast cancer and who initiated AET within 12 months of primary treatment were assessed. Adherence was measured as the proportion of days covered (PDC) over a 12-month period. Simultaneous multivariable quantile regression was used to assess the association between treatment and demographic factors, use of mail order pharmacies, medication switching, and out-of-pocket costs and adherence. The effect of each variable was examined at the 40th, 60th, 80th, and 95th quantiles. RESULTS Among the 6,863 women in the cohort, mail order pharmacies had the greatest influence on adherence at the 40th quantile, associated with a 29.6% (95% CI = 22.2–37.0) higher PDC compared with retail pharmacies. Out-of-pocket cost for a 30-day supply of AET greater than $20 was associated with an 8.6% (95% CI = 2.8–14.4) lower PDC versus $0-$9.99. The main factors that influenced adherence at the 95th quantile were mail order pharmacies, associated with a 4.4% higher PDC (95% CI = 3.8-5.0) versus retail pharmacies, and switching AET medication 2 or more times, associated with a 5.6% lower PDC versus not switching (95% CI = 2.3–9.0). CONCLUSIONS Factors associated with adherence

    Purpose: The purpose of this guideline was to provide a clinical framework for the use of radiation therapy after radical prostatectomy as adjuvant or salvage therapy. Methods and Materials: A systematic literature review using PubMed, Embase, and Cochrane database was conducted to identify peer-reviewed publications relevant to the use of radiation therapy after prostatectomy. The review yielded 294 articles; these publications were used to create the evidence-based guideline statements. Additional guidance is provided as Clinical Principles when insufficient evidence existed. Results: Guideline statements are provided for patient counseling, use of radiation therapy in the adjuvant and salvage contexts, defining biochemical recurrence, and conducting a restaging evaluation. Conclusions: Physicians should offer adjuvant radiation therapy to patients with adverse pathologic findings at prostatectomy (ie, seminal vesicle invastion, positive surgical margins, extraprostatic extension) and salvage radiation therapy to patients with prostate-specific antigen (PSA) or local recurrence after prostatectomy in whom there is no evidence of distant metastatic disease. The offer of radiation therapy should be made in the context of a thoughtful discussion of possible short- and long-term side effects of radiation therapy as well as the potential benefits of preventing recurrence. The decision to administer radiation therapy should be made by the patient and the multidisciplinary treatment team with full consideration of the patient's history, values, preferences, quality of life, and functional status. The American Society for Radiation Oncology and American Urological Association websites show this guideline in its entirety, including the full literature review.

    Background Positive esophageal proximal resection margin (ERM+) following esophagectomy was considered as incomplete or R1 resection. The clinicopathological data and long-term prognosis of esophageal cancer (EC) patients with ERM+ after esophagectomy were still unknown. Therefore, the aim of this study was to assess the clinical significance of ERM+ and its therapeutic option. Methods From November 2008 to December 2014, 3,594 patients with histologically confirmed EC underwent radical resection in our department. Among them there were 37 patients (1.03%) who had ERM+. ERM+ was defined as carcinoma or atypical hyperplasia (severe or moderate) at the residual esophageal margin in our study. For comparison, another 74 patients with negative esophageal proximal resection margin (ERM−) were propensity-matched at a ratio of 1:2 as control group according to sex, age, tumor location and TNM staging. The relevant prognostic factors were investigated by univariate and multivariate regression analysis. Results In this large cohort of patients, the rate of ERM+ was 1.03%. The median survival time was 35.000 months in patients with ERM+, significantly worse than 68.000 months in those with ERM− (Chi-square =4.064, P=0.044). Survival in patients with esophageal residual atypical hyperplasia (severe or moderate) was similar to those with esophageal residual carcinoma. Survival rate in stage I–II was higher than that in stage III–IV (Chi-square =27.598, P=0.000) in ERM−; But there was no difference between the two subgroups of patients in ERM+. Furthermore, in those patients with ERM+, survival was better in those who having adjuvant therapy, compared to those without adjuvant therapy (Chi-square =5.480, P=0.019). And the average survival time which was improved to a well situation for ERM+ patients who have adjuvant therapy was 68.556 months which is comparable to average survival time (65.815 months) of ERM− for those patients who are at earlier stages

    Between 1977 and 1980, 118 breast cancer patients with locally advanced disease, T3B-4, any N, M0 or T1-3, tumor positive axillary apex biopsy, were randomized to one of three arms: I: radiotherapy (RT) to the breast and adjacent lymph node areas; II: RT followed by 12 cycles of cyclophosphamide, methotrexate, 5 fluorouracil (CMF) and tamoxifen during the chemotherapy period; III: 2 cycles of adriamycin and vincristine (AV), alternated with 2 cycles of CMF, then RT, followed by another 4 cycles of AV, alternated with 4 CMF; tamoxifen during the entire treatment period. The median follow-up period was 5 1/2 years. The adjuvant chemo- and hormonal therapy did not improve the overall survival; the 5-year survival was 37% for all three treatment arms. There was no statistically significant difference in RFS between the three modalities, nor when arm I was compared to arm II and III together. LR was not statistically different over the three treatment arms. In 18 of the 24 patients with LR, distant metastases appeared within a few months from the local recurrence. The menopausal status did not influence the treatment results. Dose reduction in more than 4 cycles of chemotherapy was accompanied by better results. In conclusion: adjuvant chemo- and hormonal therapy did not improve RFS and overall survival. These findings do not support the routine use of adjuvant chemo- and endocrine therapy for inoperable breast cancer.

    Non-thermal irreversible electroporation (N-TIRE) has shown promise as an ablative therapy for a variety of soft-tissue neoplasms. Here we describe the therapeutic planning aspects and first clinical application of N-TIRE for the treatment of an inoperable, spontaneous malignant intracranial glioma in a canine patient. The N-TIRE ablation was performed safely, effectively reduced the tumor volume and associated intracranial hypertension, and provided sufficient improvement in neurological function of the patient to safely undergo adjunctive fractionated radiotherapy (RT) according to current standards of care. Complete remission was achieved based on serial magnetic resonance imaging examinations of the brain, although progressive radiation encephalopathy resulted in the death of the dog 149 days after N-TIRE therapy. The length of survival of this patient was comparable to dogs with intracranial tumors treated via standard excisional surgery and adjunctive fractionated external beam RT. Our results illustrate the potential benefits of N-TIRE for in vivo ablation of undesirable brain tissue, especially when traditional methods of cytoreductive surgery are not possible or ideal, and highlight the potential radiosensitizing effects of N-TIRE on the brain.

    Purpose: Pure tubular carcinoma of the breast (PTCB) represents a distinct subtype of invasive ductal carcinoma (IDC) that is generally thought to be associated with better prognosis than even low-grade IDC. There has been controversy as to the role of adjuvant radiation therapy (RT) in this population. We hypothesized that adjuvant RT would demonstrate a survival improvement. Methods and Materials: We queried the Surveillance, Epidemiology and End Results database for the years 1992-2007 to identify patients with pure tubular carcinomas of the breast. Patient demographics, tumor characteristics, and surgical and RT treatments were collected. Survival analysis was performed using the Kaplan-Meier method for univariate comparisons and Cox proportional hazards modeling for multivariate comparisons, stratifying on the basis of age with a cutoff age of 65. Results: A total of 6465 patients were identified: 3624 (56.1%) patients underwent lumpectomy with RT (LUMP+RT), 1525 (23.6%) patients underwent lumpectomy alone (LUMP), 1266 (19.6%) patients received mastectomy alone (MAST), and 50 (0.8%) patients underwent mastectomy with RT (MAST+RT). When we compared the LUMP+RT and LUMP groups directly, those receiving adjuvant RT tended to be younger and were less likely to be hormone receptor-positive. Overall survival was 95% for LUMP+RT and 90% for LUMP patients at 5 years. For those 65 or younger, the absolute overall survival benefit of LUMP+RT over LUMP was 1% at 5 years and 3% at 10 years. On stratified multivariate analysis, adjuvant RT remained a significant predictor in both age groups (P=.003 in age {<=}65 and P=.04 in age >65 patients). Other significant unfavorable factors were older age and higher T stage (age >65 only). Conclusions: Since sufficiently powered large scale clinical trials are unlikely, we would recommend that adjuvant radiation be considered in PTCB patients age 65 or younger, although consideration of the small absolute survival benefit is

    In North America, gastric cancer is the third most common gastrointestinal malignancy and the third most lethal neoplasm overall. In Asia, gastric cancer represents an even more serious problem: in Japan, it is the most common cancer in men. The standard primary therapy for gastric cancer is surgical resection; in esophagogastric-junction (EGJ) adenocarcinoma, which is often included in studies of gastric cancer, surgery is also typically the initial management strategy. However, the rates of locoregional and distant recurrence following surgery with curative intent have remained high. Investigators have explored a variety of ways of reducing these rates and improving survival in patients with gastric and EGJ cancers. These strategies have included explorations of the optimal extent of regional lymphadenectomy at the time of gastric resection; investigation of different neoadjuvant, perioperative, and adjuvant chemotherapy regimens; use of preoperative and postoperative radiation therapy; and the use of pre- and postoperative chemoradiotherapy (CRT).To date, benefit has been seen in gastric cancer patients with the use of what is called a"D2 resection"(which includes lymph nodes of stations 7 through 12) and with adjuvant CRT (in the West) or adjuvant chemotherapy with S-1 (in Japan); and neoadjuvant CRT has been shown to have a survival benefit in patients with EGJ cancers.

    Purpose: In Radiation Therapy Oncology Group 9704, as previously published, patients with resected pancreatic adenocarcinoma received continuous infusion 5-FU and concurrent radiotherapy (5FU-RT). 5FU-RT treatment was preceded and followed by randomly assigned chemotherapy, either 5-FU or gemcitabine. This analysis explored whether failure to adhere to specified RT guidelines influenced survival and/or toxicity. Methods and Materials: RT requirements were protocol specified. Adherence was scored as per protocol (PP) or less than per protocol (therapy but before trial analysis and without knowledge of individual patient treatment outcomes. Scoring was done for all tumor locations and for the subset of pancreatic head location. Results: RT was scored for 416 patients: 216 PP and 200 patients with pancreatic head tumors, both PP score and gemcitabine treatment correlated with improved MS (p = 0.016, p = 0.043, respectively). For all tumor locations, PP score was associated with decreased risk of failure (p = 0.016) and, for gemcitabine patients, a trend toward reduced Grade 4/5 nonhematologic toxicity (p = 0.065). Conclusions: This is the first Phase III, multicenter, adjuvant protocol for pancreatic adenocarcinoma to evaluate the impact of adherence to specified RT protocol guidelines on protocol outcomes. Failure to adhere to specified RT guidelines was associated with reduced survival and, for patients receiving gemcitabine, trend toward increased nonhematologic toxicity.

    Although adverse effects and glucocorticoid resistance cripple their chronic use, glucocorticoids form the mainstay therapy for acute and chronic inflammatory disorders, and play an important role in treatment protocols of both lymphoid malignancies and as adjuvant to stimulate therapy tolerability in various solid tumors. Glucocorticoid binding to their designate glucocorticoid receptor (GR), sets off a plethora of cell-specific events including therapeutically desirable effects, such as cell death, as well as undesirable effects, including chemotherapy resistance, systemic side effects and glucocorticoid resistance. In this context, selective GR agonists and modulators (SEGRAMs) with a more restricted GR activity profile have been developed, holding promise for further clinical development in anti-inflammatory and potentially in cancer therapies. Thus far, the research into the prospective benefits of selective GR modulators in cancer therapy limped behind. Our review discusses how selective GR agonists and modulators could improve the therapy regimens for lymphoid malignancies, prostate or breast cancer. We summarize our current knowledge and look forward to where the field should move to in the future. Altogether, our review clarifies novel therapeutic perspectives in cancer modulation via selective GR targeting. PMID:27713909

    Adjuvant therapy following breast cancer surgery generally consists of either a course of chemotherapy, if the cancer lacks hormone receptors, or a course of hormonal therapy, otherwise. Here, we report a correlation between adjuvant strategy and mutated pathway patterns. In particular, we find that for breast cancer patients, pathways enriched in nonsynonymous mutations in the chemotherapy group are distinct from those of the hormonal therapy group. We apply a recently developed method that identifies collaborative pathway groups for hormone and chemotherapy patients. A collaborative group of pathways is one in which each member is altered in the same-generally large-number of samples. In particular, we find the following: (i) a chemotherapy group consisting of three pathways and a hormone therapy group consisting of 20, the members of the two groups being mutually exclusive; (ii) each group is highly enriched in breast cancer drivers; and (iii) the pathway groups are correlates of subtype-based therapeutic recommendations. These results suggest that patient profiling using these pathway groups can potentially enable the development of personalized treatment plans that may be more accurate and specific than those currently available.

    Curcuminoids are bioactive polyphenolics with potent antiinflammatory properties. Although several lines of in vitro and preclinical evidence suggest potent anticancer effects of curcuminoids, clinical findings have not been conclusive. The present randomized double-blind placebo-controlled trial aimed to evaluate the efficacy of curcuminoids as adjuvant therapy in cancer patients. Eighty subjects with solid tumors who were under standard chemotherapy regimens were randomly assigned to a bioavailability-boosted curcuminoids preparation (180 mg/day; n = 40) or matched placebo (n = 40) for a period of 8 weeks. Efficacy measures were changes in the health-related quality of life (QoL) score (evaluated using the University of Washington index) and serum levels of a panel of mediators implicated in systemic inflammation including interleukins 6 (IL-6) and 8 (IL-8), TNF-α, transforming growth factor-β (TGFβ), high-sensitivity C-reactive protein (hs-CRP), calcitonin gene-related peptide (CGRP), substance P and monocyte chemotactic protein-1 (MCP-1). Curcuminoid supplementation was associated with a significantly greater improvement in QoL compared with placebo (p < 0.001). Consistently, the magnitude of reductions in TNF-α (p < 0.001), TGFβ (p < 0.001), IL-6 (p = 0.061), substance P (p = 0.005), hs-CRP (p < 0.001), CGRP (p < 0.001) and MCP-1 (p < 0.001) were all significantly greater in the curcuminoids versus placebo group. In contrast, the extent of reduction in serum IL-8 was significantly greater with placebo versus curcuminoids (p = 0.012). Quality of life variations were associated with changes in serum TGFβ levels in both correlation and regression analyses. Adjuvant therapy with a bioavailable curcuminoid preparation can significantly improve QoL and suppress systemic inflammation in patients with solid tumors who are under treatment with standard chemotherapy protocols.

    The objective of this review is to evaluate the evidence regarding the use of music as an adjuvant therapy for pain control in hospitalized adults. The search terms music, music therapy, pain, adults, inpatient, and hospitalized were used to search the Cochrane Library, Cinahl, Medline, Natural Standard, and Scopus databases from January 2005 to March 2011. (A systematic review conducted by the Cochrane Collaboration has extensively covered the time frame from 1966 to 2004.) Seventeen randomized controlled trials met criteria for review and inclusion. Seven of the research studies were conducted with surgical patients, three with medical patients, one with medical-surgical patients, four with intensive care patients, and two with pregnant patients. The combined findings of these studies provide support for the use of music as an adjuvant approach to pain control in hospitalized adults. The use of music is safe, inexpensive, and an independent nursing function that can be easily incorporated into the routine care of patients. PMID:23107431

    Purpose: In randomized trials patients with resected nonmetastatic gastric cancer who received adjuvant chemotherapy and radiotherapy (chemoRT) had better survival than those who did not. We investigated the effectiveness of adjuvant chemoRT after gastric cancer resection in an elderly general population and its effects by stage. Methods and Materials: We identified individuals in the Surveillance, Epidemiology, and End Results-Medicare database aged 65 years or older with Stage IB through Stage IV (M0) gastric cancer, from 1991 to 2002, who underwent gastric resection, using multivariate modeling to analyze predictors of chemoRT use and survival. Results: Among 1,993 patients who received combined chemoRT or no adjuvant therapy after resection, having a later year of diagnosis, having a more advanced stage, being younger, being white, being married, and having fewer comorbidities were associated with combined treatment. Among 1,476 patients aged less than 85 years who survived more than 4 months, the 313 who received combined treatment had a lower mortality rate (hazard ratio, 0.83; 95% confidence interval, 0.71-0.98) than the 1,163 who received surgery alone. Adjuvant therapy significantly reduced the mortality rate for Stages III and IV (M0), trended toward improved survival for Stage II, and showed no benefit for Stage IB. We observed trends toward improved survival in all age categories except 80 to 85 years. Conclusions: The association of combined adjuvant chemoRT with improved survival in an overall analysis of Stage IB through Stage IV (M0) resected gastric cancer is consistent with clinical trial results and suggests that, in an elderly population, adjuvant chemoradiotherapy is effective. However, our observational data suggest that adjuvant treatment may not be effective for Stage IB cancer, is possibly appropriate for Stage II, and shows significant survival benefits for Stages III and IV (M0) for those aged less than 80 years.

    Purpose: The optimal management of oral cavity squamous cell carcinoma (OCSCC) typically involves surgical resection followed by adjuvant radiotherapy or chemoradiotherapy (CRT) in the setting of adverse pathologic features. Intensity-modulated radiation therapy (IMRT) is frequently used to treat oral cavity cancers, but published IMRT outcomes specific to this disease site are sparse. We report the Dana-Farber Cancer Institute experience with IMRT-based treatment for OCSCC. Methods and Materials: Retrospective study of all patients treated at Dana-Farber Cancer Institute for OCSCC with adjuvant or definitive IMRT between August 2004 and December 2009. The American Joint Committee on Cancer disease stage criteria distribution of this cohort included 5 patients (12%) with stage I; 10 patients (24%) with stage II (n = 10, 24%),; 14 patients (33%) with stage III (n = 14, 33%),; and 13 patients (31%) with stage IV. The primary endpoint was overall survival (OS); secondary endpoints were locoregional control (LRC) and acute and chronic toxicity. Results: Forty-two patients with OCSCC were included, 30 of whom were initially treated with surgical resection. Twenty-three (77%) of 30 surgical patients treated with adjuvant IMRT also received concurrent chemotherapy, and 9 of 12 (75%) patients treated definitively without surgery were treated with CRT or induction chemotherapy and CRT. With a median follow-up of 2.1 years (interquartile range, 1.1-3.1 years) for all patients, the 2-year actuarial rates of OS and LRC following adjuvant IMRT were 85% and 91%, respectively, and the comparable results for definitive IMRT were 63% and 64% for OS and LRC, respectively. Only 1 patient developed symptomatic osteoradionecrosis, and among patients without evidence of disease, 35% experienced grade 2 to 3 late dysphagia, with only 1 patient who was continuously gastrostomy-dependent. Conclusions: In this single-institution series, postoperative IMRT was associated with promising LRC

    Although a benign disorder, pigmented villonodular synovitis (PVNS) has a high rate of recurrence. Because of the high incidence of recurrence and concern about destruction of the affected joint, several adjuvant therapies have been promoted without a clear standard treatment strategy. We reviewed cases of PVNS affecting the ankle and hindfoot joints (ankle and/or subtalar joints) treated with surgical resection without adjuvant therapy in an effort to identify the incidence of PVNS recurrence after excision without adjuvant therapy. Of the 10 cases with a mean follow-up duration of 33.2 ± 19.8 months, 4 (40%) developed a recurrence, with a mean interval of 6 (range 3 to 14) months. At the final follow-up visit, the mean American Orthopaedic Foot and Ankle Society ankle-hindfoot score was 86.6 ± 12. The clinical outcomes of PVNS affecting the ankle and hindfoot joints are associated with a relatively high incidence of recurrence, and additional clinical investigation comparing the incidence of recurrence in patients undergoing excision versus excision with adjuvant therapy is needed for us to better understand this condition and provide more informed recommendations to our patients.

    Purpose The After Mapping of the Axilla: Radiotherapy or Surgery? (AMAROS) phase III study compares axillary lymph node dissection (ALND) and axillary radiation therapy (ART) in early breast cancer patients with tumor-positive sentinel nodes. In the ART arm, the extent of nodal involvement remains unknown, which could have implications on the administration of adjuvant therapy. In this preliminary analysis, we studied the influence of random assignment to ALND or ART on the choice for adjuvant treatment. Patients and Methods In the first 2,000 patients enrolled in the AMAROS trial, we analyzed the administration of adjuvant systemic therapy. Multivariate analysis was used to assess variables affecting the administration of adjuvant chemotherapy. Adjuvant therapy was applied according to institutional guidelines. Results Of 2,000 patients, 566 patients had a positive sentinel node and were treated per random assignment. There was no significant difference in the administration of adjuvant systemic therapy. In the ALND and ART arms, 58% (175 of 300) and 61% (162 of 266) of the patients, respectively, received chemotherapy. Endocrine therapy was administered in 78% (235 of 300) of the patients in the ALND arm and in 76% (203 of 266) of the patients in the ART arm. Treatment arm was not a significant factor in the decision, and no interactions between treatment arm and other factors were observed. Multivariate analysis showed that age, tumor grade, multifocality, and size of the sentinel node metastasis significantly affected the administration of chemotherapy. Within the ALND arm, the extent of nodal involvement remained not significant in a sensitivity multivariate analysis. Conclusion Absence of knowledge regarding the extent of nodal involvement in the ART arm appears to have no major impact on the administration of adjuvant therapy. PMID:20038733

    An adjuvant rectal carcinoma study compared four postoperative treatment regimens: (1) control (no adjuvant therapy); (2) chemotherapy alone consisting of pulses of 5-fluorouracil and methyl CCNU for 18 months; (3) pelvic and perineal radiotherapy using parallel opposed fields with 4000 rad in 4.5 to 5 weeks or 4800 rad in 5 to 5.5 weeks; and (4) a combination of both modalities. The results of this study are published elsewhere and show a significantly reduced recurrence rate and prolonged disease-free survival time for the combined modality arm compared with the no therapy arm. Severe toxicity in the combined therapy arm was significantly worse (P less than 0.001) than in either single modality arm. Most of the differences in toxicity experienced between the three regimens involved diarrhea, thrombocytopenia, and leukopenia. Analysis of all parameters of radiotherapy quality assurance data was not significantly associated with toxicity. Radiation enteritis was noted in 5 patients of 96 (5.2%) in the two arms containing irradiation. All five required laparotomy. The two enteritis fatalities occurred late at 605 and 1000 days after start of combined modality treatment, respectively. One other patient on the chemotherapy arm died of acute nonlymphocytic leukemia. The authors conclude that combined radiotherapy and chemotherapy, although significantly more effective in reducing recurrence than no therapy, is significantly more toxic than single-modality therapy in many parameters, although most of the toxicity is transient and therefore not limiting. Late complications, which are less reversible and therefore much more important than early reactions, and radiation enteritis in this study were relatively uncommon. This schedule of combined modality therapy is not only effective but appears to have tolerable toxicity, because of the relative lack of late effects.

    Purpose: Patients with recurrent malignant gliomas treated with stereotactic radiosurgery (SRS) and multiagent systemic therapies were reviewed to determine the effects of patient- and treatment-related factors on survival and toxicity. Methods and Materials: A retrospective analysis was performed on patients with recurrent malignant gliomas treated with salvage SRS from September 2002 to March 2010. All patients had experienced progression after treatment with temozolomide and radiotherapy. Salvage SRS was typically administered only after multiple postchemoradiation salvage systemic therapies had failed. Results: 63 patients were treated with SRS for recurrent high-grade glioma; 49 patients had World Health Organization (WHO) Grade 4 disease. Median follow-up was 31 months from primary diagnosis and 7 months from SRS. Median overall survival from primary diagnosis was 41 months for all patients. Median progression-free survival (PFS) and overall survival from SRS (OS-SRS) were 6 and 10 months for all patients, respectively. The 1-year OS-SRS for patients with Grade 4 glioma who received adjuvant (concurrent with or after SRS) bevacizumab was 50% vs. 22% for patients not receiving adjuvant bevacizumab (p = 0.005). Median PFS for patients with a WHO Grade 4 glioma who received adjuvant bevacizumab was 5.2 months vs. 2.1 months for patients who did not receive adjuvant bevacizumab (p = 0.014). Karnofsky performance status (KPS) and age were not significantly different between treatment groups. Treatment-related Grade 3/4 toxicity for patients receiving and not receiving adjuvant BVZ was 10% and 14%, respectively (p = 0.58).On multivariate analysis, the relative risk of death and progression with adjuvant bevacizumab was 0.37 (confidence interval [CI] 0.17-0.82) and 0.45 (CI 0.21-0.97). KPS >70 and age <50 years were significantly associated with improved survival. Conclusions: The combination of salvage radiosurgery and bevacizumab to treat recurrent malignant

    Cancers of esophagus and stomach are common malignant diseases worldwide, and they are associated with serious morbidity and high mortality rates. When diagnosed at an early stage, gastro-esophageal cancers are potentially curable. Neo-adjuvant or adjuvant therapies using both chemotherapy and radiation therapy have been shown to reduce the risk of local recurrence and distant metastasis. For advanced or metastatic tumors, systemic chemotherapy offers symptomatic palliation and moderate benefits in survival. With recent advances in anti-cancer therapeutics, progress has been made to improve treatment response and life expectancy in patients with advanced gastro-esophageal cancers. Furthermore, the clinical use of molecularly targeted agents in combination with cytotoxic chemotherapeutics is being evaluated in a number of ongoing clinical trials. In this article, we review currently used standard systemic therapies including recently evolving targeted therapies for metastatic gastro-esophageal cancers, as well as the proven role and the regimens that are used as neoadjuvant and adjuvant treatment in localized gastro-esophageal cancers.

    Purpose Little is known about why women with breast cancer who have surgery do not receive proven effective postsurgical adjuvant treatments. Methods We surveyed 258 women who recently underwent surgical treatment at six New York City hospitals for early-stage breast cancer about their care, knowledge, and beliefs about breast cancer and its treatment. As per national guidelines, all women should have received adjuvant treatment. Adjuvant treatment data were obtained from inpatient and outpatient charts. Factor analysis was used to create scales scored to 100 of treatment beliefs and knowledge, medical mistrust, and physician communication about treatment. Bivariate and multivariate analyses assessed differences between treated and untreated women. Results Compared with treated women, untreated women were less likely to know that adjuvant therapies increase survival (on a 100-point scale; 66 v 75; P < .0001), had greater mistrust (64 v 53; P = .001), and had less self-efficacy (92 v 97; P < .05); physician communication about treatment did not affect patient knowledge of treatment benefits (r = 0.8; P = .21). Multivariate analysis found that untreated women were more likely to be 70 years or older (adjusted relative risk [aRR], 1.11; 95% CI, 1.00 to 1.13), to have comorbidities (aRR, 1.10; 95% CI, 1.04 to 1.12), and to express mistrust in the medical delivery system (aRR, 1.003; 95% CI, 1.00 to 1.007), even though they were more likely to believe adjuvant treatments were beneficial (aRR, 0.99; 95% CI, 0.98 to 0.99; model c, 0.84; P ≤ .0001). Conclusion Patient knowledge and beliefs about treatment and medical mistrust are mutable factors associated with underuse of effective adjuvant therapies. Physicians may improve cancer care by ensuring that discussions about adjuvant therapy include a clear presentation of the benefits, not just the risks of treatment, and by addressing patient trust in and concerns about the medical system.

    Conventional resting left ventricular ejection fraction (LVEF) assessments have limitations for detecting doxorubicin (DOX)-related cardiac dysfunction. Novel resting echocardiographic parameters, including 3-dimen-sional echocardiography (3DE) and global longitudinal strain (GLS), have potential for early identification of chemotherapy-related myocardial injury. Exercise “stress” is an established method to uncover impairments in cardiac function but has received limited attention in the adult oncology setting. We evaluated the utility of an integrated approach using 3DE, GLS, and exercise stress echocardiography for detecting subclinical cardiac dysfunction in early breast cancer patients treated with DOX-containing chemotherapy. Fifty-seven asymptomatic women with early breast cancer (mean 26 ± 22 months post-chemotherapy) and 20 sex-matched controls were studied. Resting left ventricular (LV) function was assessed by LVEF using 2-dimensional echocardiography (2DE) and 3DE and by GLS using 2-dimensional speckle-tracking echocardiography (2D-STE). After resting assessments, subjects completed cardiopulmonary exercise testing with stress 2DE. Resting LVEF was lower in patients than controls by 3DE (55 ± 4 vs. 59 ± 5 %; p = 0.005) but not 2DE (56 ± 4 vs. 58 ± 3 %; p = 0.169). 10 of 51 (20 %) patients had GLS greater than or equal to −17 %, which was below the calculated lower limit of normal (control mean 2SD); this patient subgroup had a mean 20 % impairment in GLS (−16.1 ± 0.9 vs. −20.1 ± 1.5 %; p < 0.001), despite similar LVEF by 2DE and 3DE compared to controls (p > 0.05). Cardiopulmonary function (VO2peak) was 20 % lower in patients than controls (p < 0.001). Exercise stress 2DE assessments of stroke volume (61 ± 11 vs. 69 ± 15 ml; p = 0.018) and cardiac index (2.3 ± 0.9 vs. 3.1 ± 0.8 1 min−1 m−2 mean increase; p = 0.003) were lower in patients than controls. Post-exercise increase in cardiac index predicted VO2peak (r = 0.429, p = 0

    Objective To make recommendations on the use of neoadjuvant or adjuvant therapy in addition to surgery in patients with resectable gastric cancer (T1–4, N1–2, M0). Options Neoadjuvant or adjuvant treatments compared with “curative” surgery alone. Outcomes Overall survival, disease-free survival, and adverse effects. Evidence The MEDLINE, CANCERLIT and Cochrane Library databases and relevant conference proceedings were searched to identify randomized trials. Values Evidence was selected and reviewed by one member of the Cancer Care Ontario Practice Guidelines Initiative (CCOPGI) Gastrointestinal Cancer Disease Site Group and methodologists. A systematic review of the published literature was combined with a consensus process around the interpretation of the evidence in the context of conventional practice, to develop an evidence-based practice guideline. This report has been reviewed and approved by the Gastrointestinal Cancer Disease Site Group, comprising medical oncologists, radiation oncologists, surgeons, a pathologist and 2 community representatives. Benefits, harms and costs When compared with surgery alone, at 3 years adjuvant chemoradiotherapy has been shown to increase overall survival by 9% (50% v. 41%, p = 0.005) and to improve relapse-free survival from 31% to 48% (p = 0.001). At 5 years, it has been shown to increase overall survival by 11.6% (40% v. 28.4%) and to improve relapse-free survival from 25% to 38% (p < 0.001). Treatment has been associated with toxic deaths in 1% of patients. The most frequent adverse effects (> grade 3 [Southwest Oncology Group toxicity scale] are hematologic (54%), gastrointestinal (33%), influenza-like (9%), infectious (6%) and neurologic (4%). The radiation fields used can possibly damage the left kidney, resulting in hypertension and other renal problems. Furthermore, this therapy could increase the demand on radiation resources. Physicians and patients should understand the tradeoffs between survival benefit

    Purpose: There are conflicting studies of the impact of androgen deprivation therapy (ADT) on cardiovascular (CV) mortality among prostate cancer patients receiving curative intent external beam radiation therapy (EBRT). We assessed the impact of ADT on CV mortality in patients treated in British Columbia. Methods and Materials: Provincial pharmacy and radiotherapy databases were linked to the provincial cancer registry, and defined a cohort of patients treated with curative intent EBRT between 1998 and 2005. We determined the duration of ADT and the cumulative incidence of CV death. We compared death from CV disease with and without ADT, and by duration of ADT using competing risk analysis and Fine and Gray multivariant analysis. A total of 600 randomly selected patients were reviewed to determine baseline CV disease, CV risk factors, and Charlson Index. Results: Of 5,948 prostate cancer patients treated with radical intent EBRT, of whom 1,933 were treated without ADT, 674 received ADT for {<=}6 months and 3,341 received > 6 months of ADT. The cumulative CV mortality at 7 years was 2.6% (95% confidence interval [CI] 1.9-3.5%), 2.1% (95% CI = 1.2-3.5%), and 1.4 (95% CI = 1.0-2.0%) for patients with no ADT, {<=}6 months of ADT, and >6 months of ADT, respectively (Gray's p = 0.002). Baseline CV disease and risk factors were more prevalent in the no-ADT group compared with the >6-month ADT group. Conclusions: This study demonstrated a lower CV mortality rate among patients treated with longer durations of ADT than those treated without ADT. These differences likely relate to selection of patients for ADT rather than effect of ADT itself.

    Purpose: Adjuvant radiation therapy (RT) in early-stage high- to intermediate-risk endometrioid adenocarcinoma is well established and has been shown to improve locoregional control. Its role in the management of early-stage clear cell carcinoma and uterine papillary serous carcinoma (UPSC) remains controversial. Methods and Materials: Using the Surveillance Epidemiology and End Results database, we identified women with American Joint Committee on Cancer Stage Sixth Edition. Stage IA-IIB clear cell carcinoma or UPSC who underwent hysterectomy with or without adjuvant RT between 1988 and 2003. We used Kaplan-Meier and Cox regression analysis to compare overall survival (OS) for all patients. Results: We identified 1,333 women of whom 451 had clear cell carcinoma and 882 had UPSC. Of those patients, 775 underwent surgery alone and 558 received adjuvant RT as well. For Stages I-IIB disease, the median OS with surgery alone was 106 months, vs. 151 months with adjuvant RT (p = 0.006). On subgroup analysis, we saw the benefit from adjuvant RT only in Stage IB-C patients. For Stage IB disease, patients undergoing surgery alone had a median OS of 117 months, vs. median survival not reached with the addition of RT (p = 0.006). For Stage IC disease, surgery alone had a median OS of 35 months vs. 120 months with RT (p = 0.001). Although the apparent benefit of RT diminished when measured via multivariate analysis, the impact of RT on survival did show a trend toward significance (hazard ration 0.808, confidence interval 95% 0.651-1.002, p = 0.052) Conclusion: In FIGO Stage IB-C papillary serous and clear cell uterine carcinoma, adjuvant RT seems to play an important role in improving survival.

    Malignant salivary gland tumors are rare in children, mostly represented by low-grade mucoepidermoid carcinomas. For these patients, long-term survival rates above 95% are reported after surgical resection. Here we report a case of a 9-year-old girl with a high grade locally advanced mucoepidermoid carcinoma undergoing adjuvant radiotherapy and chemotherapy after surgery. We emphasize the controversy and lack of evidence-based indication for these highly toxic adjuvant therapy modalities in children. PMID:27746885

    There is no consensus regarding the timing of adjuvant radioactive iodine therapy (RAI) therapy in low- and intermediate-risk papillary thyroid carcinoma (PTC). We analyzed the impact of adjuvant RAI on overall survival (OS) in low- and intermediate-risk PTC. The National Cancer Data Base was queried from 2004 to 2011 for pN0M0 PTC patients having near/subtotal or total thyroidectomy and adjuvant RAI. Tumors ≤1 cm with negative margins were low risk while 1.1- to 4-cm tumors with negative margins or ≤1 cm with microscopic margins were termed intermediate risk. RAI in ≤3 months and between 3 and 12 months was termed as early and delayed, respectively. Survival analysis was performed after adjusting for patient and tumor-related variables. There were 7,306 low-risk and 16,609 intermediate-risk patients. Seventeen per cent low-risk and 15 per cent intermediate-risk patients had delayed RAI. Kaplan-Meier analysis did not show a difference in OS for early versus delayed RAI administration in low- (10-year OS 94.5% vs 94%, P = 0.627) or intermediate-risk (10-year OS 95.3% vs 95.9%, P = 0.944) patients. In adjusted survival analysis, RAI timing did not affect OS in all patients (hazard ratios = 0.98, 95% confidence interval = 0.71-1.34, P = 0.887). In conclusion, the timing of postthyroidectomy adjuvant RAI therapy does not affect OS in low- or intermediate-risk PTC. PMID:27670568

    Oxygen is an essential gas. Oxygen is also a biological medicine. Hyperbaric oxygen therapy is a treatment which is based on the respiration of pure oxygen in a particular pressurised environment (hyperbaric chamber). The pressure allows the diffusion of oxygen into the blood at a concentration which is ten/fifteen/twenty times the normal level. The increase in oxygen in bodily liquids stimulates the synthesis of a gas, nitric oxide (NO), which has a powerful anti-inflammatory effect and promotes the formation of new blood vessels (also through the employment of stem cells) thus accelerating the healing of wounds. Hyperbaric oxygen therapy reactivates metabolic processes which have stopped and is able to help the recovery and obvious improvement of patients suffering from several serious illnesses. Hyperbaric oxygen therapy is a medicine, and as such requires careful dosage, monitoring of its results, and prevention of possible side effects.

    Multiple adjuvant regimens are used for HER2+ breast cancer, but experience in routine practice is not reported. We evaluated whether oncologists’ perceptions of these regimens matches clinical experience. We surveyed Wisconsin medical oncologists throughout the state regarding factors impacting selection of TCH (docetaxel, carboplatin, trastuzumab) or anthracycline-based therapy. We also reviewed 200 cases of HER2+ breast cancer treated at the University of Wisconsin and the Marshfield Clinic and collected data on patient and tumor characteristics, chemotherapy regimen, and toxicities. Two-thirds of surveyed oncologists prefer anthracycline-based therapy, particularly for node-positive cancers. However, TCH was preferred for early stage (T1a-bN0) tumors. Half of oncologists use prophylactic G-CSF with TCH. In the 200 cases reviewed at our centers, acute toxicity occurred more frequently with TCH. There were fewer dose modifications or delays for AC-TH (doxorubicin, cyclophosphamide, paclitaxel, trastuzumab) than TCH (31% vs. 47%, p=0.07), possibly due to higher use of prophylactic G-CSF with AC-TH (77% vs. 34% with TCH, p<0.001). Fifteen patients received prophylactic G-CSF during TCH; none developed neutropenic fever. In contrast, 25% developed neutropenic fever during TCH without G-CSF. There were modest declines in median left ventricular ejection fraction reaching 9% with AC-TH and 3% with TCH at 12 months, but early cessation of trastuzumab was similar for both regimens. We conclude that TCH and AC-TH are common adjuvant regimens used for HER2+ breast cancer. The preference of TCH for early-stage disease and anthracycline-based therapy for node-positive disease suggests that many oncologists perceive that TCH is safer and AC-TH more effective. Myelosuppression from TCH is greater than AC-TH, but can be mitigated with routine G-CSF. PMID:22065290

    Conditionally replicating adenoviruses (CRAds) utilize tissue specific promoters to control the expression of the early genes, E1A and E1B, to preferentially replicate and lyse tumor cells (oncolysis). Previous CRAds used in prostate cancer gene therapy require androgens to activate prostate specific promoters and induce viral replication. Unfortunately, these CRAds have reduced activity in patients on androgen suppressive therapy. We describe a novel prostate specific CRAd generated by fusing the E1A gene to the androgen receptor (AR) cDNA with a point mutation in codon 685 (C685Y). The E1A-AR fusion neutralizes the previously described mutual inhibition of E1A & AR, and the C685Y point mutation alters specificity of steroid ligand binding to the AR, such that both androgens and non-steroidal anti-androgens can activate viral replication. We demonstrate that the mutated E1A-AR retained the ability to function in regulating AR responsive genes and E1A responsive viral genes. In combination therapy of virus, bicalutamide (anti-androgen) and radiation, a profound impact on cell death by viral oncolysis was seen both in vitro and tumor xenografts. To our knowledge, this is the first gene therapy engineered to be enhanced by anti-androgens, and a particularly attractive adjuvant strategy for intensity modulated radiation therapy (IMRT) of high-risk prostate cancers.

    The successful translation of the scientific principles of targeting the breast tumour oestrogen receptor (ER) with the nonsteroidal anti-oestrogen tamoxifen and using extended durations (at least 5 years) of adjuvant therapy, dramatically increased patient survivorship and significantly enhanced a drop in national mortality rates from breast cancer. The principles are the same for the validation of aromatase inhibitors to treat post-menopausal patients but tamoxifen remains a cheap, life-saving medicine for the pre-menopausal patient. Results from the Oxford Overview Analysis illustrate the scientific principle of "longer is better" for adjuvant therapy in pre-menopausal patients. One year of adjuvant therapy is ineffective at preventing disease recurrence or reducing mortality, whereas five years of adjuvant tamoxifen reduces recurrence by 50% which is maintained for a further ten years after treatment stops. Mortality is reduced but the magnitude continues to increase to 30% over a 15-year period. With this clinical database, it is now possible to implement simple solutions to enhance survivorship. Compliance with long-term anti-hormone adjuvant therapy is critical. In this regard, the use of selective serotonin reuptake inhibitors (SSRIs) to reduce severe menopausal side effects may be inappropriate. It is known that SSRIs block the CYP2D6 enzyme that metabolically activates tamoxifen to its potent anti-oestrogenic metabolite, endoxifen. The selective norepinephrine reuptake inhibitor, venlafaxine, does not block CYP2D6, and may be a better choice. Nevertheless, even with perfect compliance, the relentless drive of the breast cancer cell to acquire resistance to therapy persists.

    Soft tissue sarcomas are rare mesenchymal cancers that pose a treatment challenge. Although small superficial soft tissue sarcomas can be managed by surgery alone, adjuvant radiotherapy in addition to limb-sparing surgery substantially increases local control of extremity sarcomas. Compared with postoperative radiotherapy, preoperative radiotherapy doubles the risk of a wound complication, but decreases the risk for late effects, which are generally irreversible. For retroperitoneal sarcomas, intraoperative radiotherapy can be used to safely escalate the radiation dose to the tumor bed. Patients with newly diagnosed sarcoma should be evaluated before surgery by a multidisciplinary team that includes a radiation oncologist. PMID:27591502

    Breast cancer is a life-threatening disease among women worldwide with annual rates of reported incidence and death increasing alarmingly. Chemotherapy is a recommended and effective treatment option for breast cancer; however, the narrow therapeutic indices and varied side effects of currently approved drugs present major hurdles in increasing its effectiveness. An increasing number of literature evidence indicate that complementary and alternative medicine (CAM) used in treatment-related symptom control and alleviation of side effects plays an important role in increasing survival rate and quality of life in breast cancer patients. This review focuses on the use of herbal medicines and acupuncture in palliative care and as adjuvants in the treatment of breast cancer. Herbal medicinal treatments, the correlation of clinical use with demonstrated in vitro and in vivo mechanisms of action, and the use of certain acupoints in acupuncture are summarized. The aim of this review is to facilitate an understanding of the current practice and usefulness of herbal medicine and acupuncture as adjuvants in breast cancer therapy. PMID:23840256

    Worldwide, around 14 million individuals are coinfected with both tuberculosis (TB) and human immunodeficiency virus (HIV). In coinfected individuals, both pathogens weaken immunological system synergistically through mechanisms that are not fully understood. During both HIV and TB infections, there is a chronic state of inflammation associated to dramatic changes in immune cytokine and endocrine hormone levels. Despite this, the relevance of immunoendocrine interaction on both the orchestration of an effective immune response against both pathogens and the control of the chronic inflammation induced during HIV, TB, or both infections is still controversial. The present study reviews immunoendocrine interactions occurring during HIV and TB infections. We also expose our own findings on immunoendocrine cross talk in HIV-TB coinfection. Finally, we evaluate the use of adrenal hormones and their derivatives in immune-therapy and discuss the use of some of these compounds like the adjuvant for the prevention and treatment of TB in HIV patients.

    Head and neck pain caused of benign or malignant disease reduces remarkable the patient's quality of life. In the following are presented adjuvant and medicamentous methods for pain control. Surgery, irradiation and chemotherapy aim to diminish the tumor extension and reduce algesic transmitting substances in the periphery. Nerve blocs, cryoanalgesia and transcutaneous electrical nerve stimulation lead to an interruption of the painful spinal reflex arc. Active, passive and relaxation exercises prevent from dolorific muscular tensions. Psychological treatment, so as relaxation techniques in connection with behavior therapy, helps to develop coping strategies. The mainstay of pain relief is effective use of analgetics which should be given orally if possible, on a regular schedule and on an individualized basis according with the WHO guidelines.

    Despite aggressive surgical treatment, prompt antibiotic therapy, and modern intensive care, up to one half of patients still die of diffuse peritonitis. There must be a distinction between infection as a microbiological phenomenon and sepsis as a complex, deleterious, inflammatory host response. Physiologic and metabolic changes during the latter process by taxonomically different organisms or different sources of infection are often clinically indistinguishable. Taurolidine, an amino acid derivate, seems to cover a variety of effects in peritonitis. As secondary peritonitis is associated with a significant cytokine release that is compartementalized in the peritoneal cavity, taurolidine is bactericidal, antiendotoxic, and antiadherent locally and, on the other hand, may modulate the systemic cytokine-mediated inflammatory response after being adsorbed systemically by the peritoneum. Current management of peritonitis can clear the peritoneal cavity of microorganisms and their products but patients continue to die of uncontrolled cytokine-induced systemic inflammation. In patients that undergo daily staged, planned relaparotomies they should not only be treated locally by taurolidine but also systemically by intravenous administration. The latter should, as a sort of sequential therapy, be continued, especially when the peritoneal cavity has been closed after a series of relaparotomies.

    Oxidative stress is a key component in carcinogenesis. Although radiation produces reactive oxygen species, some anticancer agents such as alkylating agents, platinum and antitumor antibiotics exert cytotoxicity by generating free radicals. Nonenzymatic exogenous antioxidants such as vitamins, minerals, and polyphenols can quench ROS activity. However, whether antioxidants alter antitumor effects during radiotherapy and some types of chemotherapy remains unclear. In the present study, we reviewed antioxidants as an adjuvant therapy for cancer patients during chemotherapy or radiotherapy. Electronic literature searches were performed to select all randomized controlled clinical trials (RCTs) in which antioxidants were administered to cancer patients along with chemotherapy or radiotherapy. Articles or abstracts written in English were included. In total, 399 reports received primary screening. Duplicated articles and those meeting the exclusion criteria (not RCT, not human, and no oral administration) were excluded. Finally, 49 reports matching the inclusion criteria were included. It was difficult to determine whether antioxidants affect treatment outcomes or whether antioxidants ameliorate adverse effects induced by chemotherapy and radiotherapy. It is desirable to use an evidence-based method to select supplements best suited to cancer patients. Although there are many opinions about risks or benefits of antioxidant supplementation, we could mostly conclude that the harm caused by antioxidant supplementation remains unclear for patients during cancer therapy, except for smokers undergoing radiotherapy.

    Purpose: To investigate the effects of adjuvant chemotherapy in nasopharyngeal carcinoma (NPC) patients with persistently detectable plasma Epstein-Barr virus DNA (pEBV DNA) after curative radiation therapy plus induction/concurrent chemotherapy. Methods and Materials: The study population consisted of 625 NPC patients with available pEBV DNA levels before and after treatment. Eighty-five patients with persistently detectable pEBV DNA after 1 week of completing radiation therapy were eligible for this retrospective study. Of the 85 patients, 33 were administered adjuvant chemotherapy consisting of oral tegafur-uracil (2 capsules twice daily) for 12 months with (n=4) or without (n=29) preceding intravenous chemotherapy of mitomycin-C, epirubicin, and cisplatin. The remaining 52 patients who did not receive adjuvant chemotherapy served as the control group. Results: Baseline patient characteristics at diagnosis (age, sex, pathologic type, performance status, T classification, N classification, and overall stage), as well as previous treatment modality, were comparable in both arms. After a median follow-up of 70 months for surviving patients, 45.5% (15 of 33 patients) with adjuvant chemotherapy and 71.2% (37 of 52 patients) without adjuvant chemotherapy experienced tumor relapses (P=.0323). There were a significant reduction in distant failure (P=.0034) but not in local or regional recurrence. The 5-year overall survival rate was 71.6% for patients with adjuvant chemotherapy and 28.7% for patients without adjuvant chemotherapy (hazard ratio 0.27; 95% confidence interval 0.17-0.55; P<.0001). Conclusions: Our retrospective data showed that adjuvant chemotherapy can reduce distant failure and improve overall survival in NPC patients with persistently detectable pEBV DNA after curative radiation therapy plus induction/concurrent chemotherapy.

    Purpose: Although chemoradiotherapy was considered the standard adjuvant treatment for gastric cancer, a recent Phase III trial (Medical Research Council Adjuvant Gastric Infusional Chemotherapy [MAGIC]) did not include radiotherapy in the randomization scheme because it was considered expendable. Given radiotherapy's potential, efforts needed to be made to optimize its use for treating gastric cancer. We assessed whether intensity-modulated radiotherapy (IMRT) could improve upon our published results in patients treated with three-dimensional (3D) conformal therapy. Methods and Materials: Fourteen patients with adenocarcinoma of the stomach were treated with adjuvant chemoradiotherapy using a noncoplanar four-field arrangement. Subsequently, a nine-field IMRT plan was designed using a CMS Xio IMRT version 4.3.3 module. Two IMRT beam arrangements were evaluated: beam arrangement 1 consisted of gantry angles of 0 deg., 53 deg., 107 deg., 158 deg., 204 deg., 255 deg., and 306 deg.. Beam arrangement 2 consisted of gantry angles of 30 deg., 90 deg., 315 deg., and 345 deg.; a gantry angle of 320 deg./couch, 30 deg.; and a gantry angle of 35{sup o}/couch, 312{sup o}. Both the target volume coverage and the dose deposition in adjacent critical organs were assessed in the plans. Dose-volume histograms were generated for the clinical target volume, kidneys, spine, and liver. Results: Comparison of the clinical target volumes revealed satisfactory coverage by the 95% isodose envelope using either IMRT or 3D conformal therapy. However, IMRT was only marginally better than 3D conformal therapy at protecting the spine and kidneys from radiation. Conclusions: IMRT confers only a marginal benefit in the adjuvant treatment of gastric cancer and should be used only in the small subset of patients with risk factors for kidney disease or those with a preexisting nephropathy.

    As the mortality rate from breast cancer decreases, the issues facing breast cancer survivors are becoming increasingly important. Survivors of all ages may face physical and psychosocial consequences of their diagnosis and treatments. However, the long-term fertility and menopause-related side-effects of adjuvant therapy uniquely affect younger premenopausal breast cancer survivors. This article provides an evidence-based overview of the reproductive and gynaecological impact of breast cancer therapy for premenopausal women diagnosed with breast cancer. The physical and psychosocial implications of premature menopause are presented. Strategies for preserving fertility in selected patients are also discussed. Recent clinical trials strongly indicate that premenopausal women with oestrogen receptor positive tumours should receive endocrine therapy. The increased use of endocrine therapies in younger women raises important questions regarding patient information needs and treatment decision-making.

    Strategies for improving the clinical efficacy of photodynamic therapy (PDT) in treatment of solid cancers include applications of different types of adjuvant treatments in addition to this modality that may result in superior therapeutic outcome. Examples of such an approach investigated using mouse tumor models are presented in this report. It is shown that the cures of PDT treated subcutaneous tumors can be substantially improved by adjuvant therapy with: metoclopramide (enhancement of cancer cell apoptosis), combretastatin A-4 (selective destruction of tumor neovasculature), Roussin's Black Salt (light activated tumor localized release of nitric oxide), or dendritic cell-based adoptive immunotherapy (immune rejection of treated tumor).

    Purpose: Long-term survival rates for patients with resected pancreatic ductal adenocarcinoma (PDAC) have stagnated at 20% for more than a decade, demonstrating the need to develop novel adjuvant therapies. Gemcitabine-erlotinib therapy has demonstrated a survival benefit for patients with metastatic PDAC. Here we report the first phase 2 study of erlotinib in combination with adjuvant chemoradiation and chemotherapy for resected PDAC. Methods and Materials: Forty-eight patients with resected PDAC received adjuvant erlotinib (100 mg daily) and capecitabine (800 mg/m{sup 2} twice daily Monday-Friday) concurrently with intensity modulated radiation therapy (IMRT), 50.4 Gy over 28 fractions followed by 4 cycles of gemcitabine (1000 mg/m{sup 2} on days 1, 8, and 15 every 28 days) and erlotinib (100 mg daily). The primary endpoint was recurrence-free survival (RFS). Results: The median follow-up time was 18.2 months (interquartile range, 13.8-27.1). Lymph nodes were positive in 85% of patients, and margins were positive in 17%. The median RFS was 15.6 months (95% confidence interval [CI], 13.4-17.9), and the median overall survival (OS) was 24.4 months (95% CI, 18.9-29.7). Multivariate analysis with adjustment for known prognostic factors showed that tumor diameter >3 cm was predictive for inferior RFS (hazard ratio, 4.01; P=.001) and OS (HR, 4.98; P=.02), and the development of dermatitis was associated with improved RFS (HR, 0.27; P=.009). During CRT and post-CRT chemotherapy, the rates of grade 3/4 toxicity were 31%/2% and 35%/8%, respectively. Conclusion: Erlotinib can be safely administered with adjuvant IMRT-based CRT and chemotherapy. The efficacy of this regimen appears comparable to that of existing adjuvant regimens. Radiation Therapy Oncology Group 0848 will ultimately determine whether erlotinib produces a survival benefit in patients with resected pancreatic cancer.

    Purpose: To report outcomes for patients with resected pancreas cancer treated with an adjuvant regimen consisting of gemcitabine-based combination chemotherapy followed by capecitabine and radiation. Patients and Methods: We performed a retrospective review of a series of patients treated at a single institution with a common postoperative adjuvant program. Between January 2002 and August 2006, 43 resected pancreas cancer patients were offered treatment consisting of 4, 21-day cycles of gemcitabine 1 g/m{sup 2} intravenously over 30 min on Days 1 and 8, with either cisplatin 35 mg/m{sup 2} intravenously on Days 1 and 8 or capecitabine 1500 mg/m{sup 2} orally in divided doses on Days 1-14. After completion of combination chemotherapy, patients received a course of radiotherapy (54 Gy) with concurrent capecitabine (1330 mg/m{sup 2} orally in divided doses) day 1 to treatment completion. Results: Forty-one patients were treated. Median progression-free survival for the entire group was 21.7 months (95% confidence interval 13.9-34.5 months), and median overall survival was 45.9 months. In multivariate analysis a postoperative CA 19-9 level of >=180 U/mL predicted relapse and death. Toxicity was mild, with only two hospitalizations during adjuvant therapy. Conclusions: A postoperative adjuvant program using combination chemotherapy with gemcitabine and either cisplatin or capecitabine followed by radiotherapy with capecitabine is tolerable and efficacious and should be considered for Phase III testing in this group of patients.

    Purpose Atypical femoral fracture (AFF), periprosthetic femoral fracture (PPFF) and femoral nonunion (FNU) are recalcitrant challenges for orthopedic surgeons. Teriparatide (TPTD) had been demonstrated to have anabolic effects on bone in various studies. We postulated that adjuvant TPTD after operation would enhance biologic stimulation for bone formation. We investigated (1) whether the adjuvant TPTD could achieve satisfactory union rate of surgically challenging cases such as displaced AFF, PPFF and FNU; (2) whether the adjuvant TPTD could promote development of abundant callus after surgical fixation; (3) whether the adjuvant TPTD had medically serious adverse effects. Materials and Methods Thirteen patients who agreed to off label use of TPTD in combination of operation were included in this retrospective case series. Median patients' age was 68.7 years, and there were three male and ten female patients. Their diagnoses were nonunion in six patients and acute fracture in seven. Medical records and radiographic images were reviewed. Results Twelve of thirteen fractures were united both clinically and radiologically within a year after adjuvant TPTD. Union completed radiologically median 5.4 months and clinically 5.7 months after the medication, respectively. Callus appeared abundantly showing median 1.4 of fracture healing response postoperatively. There was no serious adverse reaction of medication other than itching, muscle cramp, or nausea. Conclusion Even appropriate surgical treatment is a mainstay of treatment for AFF, PPFF, and FNU, the current report suggested that adjuvant TPTD combined with stable fixation results in satisfactory outcome for the challenging fractures of femur.

    Purpose: Local-regional failures (LFs) after cystectomy with or without chemotherapy are common in locally advanced disease. Adjuvant radiation therapy (RT) could reduce LFs, but toxicity has discouraged its use. Modern RT techniques with improved normal tissue sparing have rekindled interest but require knowledge of pelvic failure patterns to design treatment volumes. Methods and Materials: Five-year LF rates after radical cystectomy plus pelvic node dissection with or without chemotherapy were determined for 8 pelvic sites among 442 urothelial bladder carcinoma patients. The impact of pathologic stage, margin status, nodal involvement, and extent of node dissection on failure patterns was assessed using competing risk analysis. We calculated the percentage of patients whose sites of LF would have been completely encompassed within various hypothetical clinical target volumes (CTVs) for postoperative radiation. Results: Compared with stage {<=}pT2, stage {>=}pT3 patients had higher 5-year LF rates in virtually all pelvic sites. Among stage {>=}pT3 patients, margin status significantly altered the failure pattern whereas extent of node dissection and nodal positivity did not. In stage {>=}pT3 patients with negative margins, failure occurred predominantly in the iliac/obturator nodes and uncommonly in the cystectomy bed and/or presacral nodes. Of these patients in whom failure subsequently occurred, 76% would have had all LF sites encompassed within CTVs covering only the iliac/obturator nodes. In stage {>=}pT3 with positive margins, cystectomy bed and/or presacral nodal failures increased significantly. Only 57% of such patients had all LF sites within CTVs limited to the iliac/obturator nodes, but including the cystectomy bed and presacral nodes in the CTV when margins were positive increased the percentage of LFs encompassed to 91%. Conclusions: Patterns of failure within the pelvis are summarized to facilitate design of adjuvant RT protocols. These data suggest

    Abstract To evaluate the treatment pattern and survival of patients receiving radical resection for primary small cell carcinoma of the esophagus (PSCCE). This retrospective study included 150 patients who received radical resection of PSCCE. Data were retrieved from 4 centers in Western China. Thirty-nine of 150 patients received postoperative chemo-radiotherapy, 62 received postoperative chemotherapy, and 49 received radical resection only. The median radiation dosage was 50 Gy. The chemotherapeutic regimen was platinum-based and lasted for 2 to 6 cycles (median, 3). Median disease-free survival (mDFS) and overall survival (mOS) were 12.0 and 18.3 months, respectively. Subgroup analysis revealed that postoperative therapy did not improve survival in limited stage I (LSI) disease, whereas postoperative chemotherapy improved survival in limited stage II (LSII) disease. Relative to chemotherapy alone, chemoradiotherapy did not improve survival in patients with completely resected LSII disease. A multivariate analysis indicated an association of no postoperative chemotherapy with shorter DFS (P = 0.050) and OS (P = 0.010). Higher lymph node stage and length of disease longer than 3 cm were poor prognostic factors for both DFS and OS. Adjuvant chemotherapy improves survival in PSCCE patients with completely resected LSII disease. Adjuvant treatment with postoperative chemotherapy alone or postoperative chemo-radiotherapy does not increase survival in completely resected LSI disease. PMID:27124057

    Introduction Idiopathic Guttate Hypomelanosis (IGH) macules are hypo pigmented lesions occurring due to decreased functioning of melanocytes due to photosensitivity or persistent irritation of skin in middle aged and elderly. Aim To find out the efficacy of placental extracts when used as an adjunct with 88% phenol for the treatment of IGH macules. Materials and Methods A total of 40 patients were randomly divided into two groups (n=20 in each group), viz group P, (the control group, treated with only 88% phenol) and Group PP (study group, treated with Placental extracts along with 88% phenol). Spot peeling was done with 88% phenol in both the groups while group PP was advised to use placental extract at night for 3 months. Patients of both groups were assessed both subjectively and objectively after every session and at the end of 3 months of initiation of therapy. The statistical analysis was done using Chi-square test, Z-test and a p-value<0.05 was considered significant. Results Both the groups showed significant re-pigmentation of lesions i.e., 76.8% in group P and 79.1% in group PP; whereas, what group PP had shown was non- significantly (p=0.8203) better as compared to group P. Conclusion The clinical and patient acceptability of phenol along with the placental extracts as an adjuvant was better with similar results. Hence, the use of placental extract is recommended along with phenol in IGH lesions. PMID:27656538

    Purpose: The criteria for administration of adjuvant radiation therapy (RT) in oral cavity squamous cell carcinoma (OSCC) remain controversial, and it is unclear whether patients with pT1-3N0 disease benefit from adjuvant radiation in the presence of free margins and perineural invasion. The goal of this report was to determine whether this group would benefit from adjuvant radiation therapy in terms of 5-year local control rate and overall survival rate. Methods and Materials: We retrospectively reviewed our case records from January 1996 to May 2005. In all, 460 pT1-3N0 OSCC patients had tumor-free margins, of whom 68 had perineural invasion. Postoperative adjuvant RT was performed in patients with pT4 tumors, positive lymph nodes, or close margins ({<=}4 mm). In addition, selected OSCC patients with large pT3 tumors or perineural invasion received postoperative adjuvant RT. Local control and overall survival rates were plotted by Kaplan-Meier analysis. Results: There were no significant differences in 5-year local control (p 0.1936) and overall survival (p = 0.5580) rates between patients with perineural invasion compared with those without. Among patients with perineural invasion, the addition of adjuvant radiotherapy did not significantly alter the 5-year local control rate (p = 0.3170) or the overall survival rate (p = 0.0935). Conclusion: Altogether, these data seem to indicate that radical surgical resection alone should be considered a sufficient treatment for OSCC patients with pT1-3N0 disease, even in the presence of perineural invasion.

    Postoperative radiotherapy (RT) is the standard of care for early stage breast cancer. It reduces the risk for local recurrence and prolongs survival. We assessed whether, the omission of RT because of patient's preference may influence the prognosis and, thus, the quality of cancer care. Detailed information from a prospectively collected database of a breast cancer center was analyzed. Multiple regression analysis and univariate and multivariate analysis for risk factors for recurrence were performed. The entire cohort of primary breast cancer patients in a given time period was analyzed. Data from 1903 patients undergoing treatment at breast cancer center between 2003 and 2008 were used. All patient underwent breast conserving surgery and RT was performed for all patients of the cohort. Local tumor control and disease-free survival were calculated. After a median follow-up of 2.18 years (maximum 6.39 years), 5.5% of patients did not follow guideline-based recommendations for RT. There was a significant correlation between noncompliance and patient's age, adjuvant hormonal therapy (97.0%), and adjuvant chemotherapy (96.8%). Seventy local recurrences occurred that corresponds to a local recurrence rate of 3.9%. The difference in regard to local recurrence-free 5-year survival between the compliant patients and the noncompliant patients is absolute 17.9 (93.3% and 75.4%). Noncompliant patients had suffered a 5.02-fold increased risk of local recurrence than compliant patients. The omission of RT after breast-conserving surgery results in a higher local failure rate and significantly worsens clinical outcome. Age may play an important role because of the comorbidities of aged patients or the assumed low RT tolerance in this group. On a clinical level, this data suggests that improvement is needed to correct this situation, and the question remains as to how best to improve RT compliance.

    Gastric cancer is one of the main cancer-related causes of death worldwide. The curative treatment of gastric cancer consists of tumor resection and lymphadenectomy. However, surgical treatment alone is associated with high recurrence rates. Adjuvant treatment strategies have been studied over the last decades, but there have been controversial results from the initial studies. The pivotal INT0116 study demonstrated that the use of adjuvant chemoradiotherapy with 5-fluorouracil increases relapse-free and overall survival, and it has been adopted across the Western world. The high toxicity of radiochemotherapy and suboptimal surgical treatment employed, with fewer than 10% of the patients submitted to D2 lymphadenectomy, were the main study limitations. Since its publication, other adjuvant treatment modalities have been studied, and radiochemotherapy is being refined to improve its efficacy and safety. A multimodal approach has been demonstrated to significantly increase relapse-free and overall survival, and it can be offered in the form of perioperative chemotherapy, adjuvant chemoradiotherapy or adjuvant chemotherapy, regardless of the extent of lymphadenectomy. The objective of the present review is to report the major advances obtained in the last decades in the adjuvant treatment of gastric cancer as well as the perspectives of treatment based on recent knowledge of the molecular biology of the disease.

    Objective This study aims to find out the safety and efficiency of postoperative adjuvant transarterial chemoembolization (TACE) and radiotherapy (RT) in hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT). Methods From 2009 to 2010, a total of 92 HCC patients with PVTT were enrolled in this retrospective study. Patients were divided into three groups according to their adjuvant therapies (conservative group, n=51; TACE group, n=31; RT group, n=10). Results In our analysis, median survival in patients with postoperative adjuvant TACE (21.91±3.60 months) or RT (14.53±1.61 months) was significantly longer than patients with hepatectomy alone (8.99±1.03 months). But the difference between adjuvant TACE and RT was of no significance (P=0.716). Also a similar result could be observed in median disease-free survival: conservative group (6.51±1.44 months), TACE group (13.98±3.38 months), and RT group (14.03±2.40 months). Treatment strategies (hazard ratio [HR] =0.411, P<0.001) and PVTT type (HR =4.636, P<0.001) were the independent prognostic factors for overall survival. Similarly, the risk factors were the same when multivariate analysis was conducted in disease-free survival (treatment strategies, HR =0.423, P<0.001; PVTT type, HR =4.351, P<0.001) and recurrence (treatment strategies, HR =0.459, P=0.030; PVTT type, HR =2.908, P=0.047). Patients with PVTT type I had longer overall survival than patients with PVTT type II (median survival: 18.43±2.88 months vs 11.59±1.45 months, P=0.035). Conclusion Postoperative adjuvant TACE and RT may be a choice for HCC patients with PVTT. PMID:27390524

    Wide local excision is considered routine therapy after initial diagnosis of primary melanoma to reduce local recurrences, but it does not impact survival. Sentinel node staging is recommended for melanomas of intermediate thickness, but it has also not demonstrated any indisputable therapeutic effect on survival. The prognostic value of sentinel node staging has been long established and is therefore considered routine, especially in light of the eligibility criteria for adjuvant therapy (trials). Whether completion lymph node dissection after a positive sentinel node biopsy improves survival is the question of current trials. The MSLT-2 study is best powered to show a potential benefit, but it has not yet reported any data. Another study, the German DECOG study, presented at the 2015 American Society of Clinical Oncology (ASCO) Annual Meeting did not show any benefit but is criticized for the underpowered design and insufficient follow-up. There is no consensus on the use of adjuvant interferon in melanoma. This topic has been the focus of many studies with different regimens (low-, intermediate-, or high-dose and/or short- or long-term treatment). Adjuvant interferon has been shown to improve relapse-free survival but failed to improve overall survival. More recently, adjuvant ipilimumab has also demonstrated an improved relapse-free survival. Overall survival data have not yet been reported due to insufficient follow-up. Currently, studies are ongoing to analyze the use of adjuvant anti-PD-1 and molecular targeted therapies (vemurafenib, dabrafenib, and trametinib). In the absence of unambiguously positive approved agents, clinical trial participation remains a priority. This could change in the near future. PMID:27249760

    of Background Data The effectiveness of adjuvant chemotherapy in patients with stage II/III colorectal cancer has been confirmed in various studies. However, no adjuvant chemotherapy for colorectal liver metastasis (CLM) classified to stage IV has been established. Objectives We conducted a phase 1 study of S-1 and oxaliplatin to determine the recommended dose (RD) in patients with CLM as adjuvant therapy in two institutes. Methods S-1 and oxaliplatin were administered from day 1 to day 14 of a 3-week cycle as a 2-h infusion every 3 weeks, respectively. The initial doses of S-1 and oxaliplatin were fixed to 80 mg/m(2) and 100 mg/m(2), respectively (level 1). We scheduled in the protocol a dose change of S-1 and oxaliplatin to level 2 (S-1: 80 mg/m(2) and oxaliplatin: 130 mg/m(2)) or level 0 (S-1: 65 mg/m(2) and oxaliplatin: 100 mg/m(2)) depending on the incidence of dose-limiting toxicity (DLT) at level 1 in six patients. Results Because DLT occurred in one among the initial six patients at level 1, the doses were increased to level 2 in the next six patients. At level 2, grade 3 leukopenia and neutropenia occurred in one (16.7 %) and two (33.3 %) patients, respectively, in the absence of non-hematological event. Because no DLT occurred at level 2, we suggest that the RD can be set to the level 2 dose. The median number of cycles delivered at RD was 8. The mean relative dose intensity of S-1 and oxaliplatin at RD was 0.90 and 0.63, respectively. Conclusion In a patient undergoing hepatectomy for CLM, 80 mg/m(2) of S-1 and 130 mg/m(2) of oxaliplatin are recommended as adjuvant therapy. A further study is required to confirm the efficacy and safety of this regimen on a larger scale.

    Breast cancer metastases appearing soon after adjuvant chemotherapy (within 12 months of its completion) are usually resistant to retreatment with the same cytotoxic agents, while relapses occurring later (beyond 12 months) regress when rechallenged with the same agents, showing similar response rates observed in non-pretreated patients with advanced disease. The International Breast Cancer Study Group (IBCSG) prospectively explored the efficacy of retreatment for patients upon relapse using the same therapy administered during the adjuvant programme. 87 patients previously treated with an adjuvant CMF (cyclophosphamide, methotrexate, 5-fluorouracil) combination chemotherapy (with or without the addition of low-dose prednisone and tamoxifen), who had measurable first breast cancer relapse, usually after at least 6 months of completion of the adjuvant treatment, were treated with CMF. Pretreatment consisted of 1-3 CMF courses in 27 patients and 4 or more courses in 60 patients. 17 patients were retreated with additional tamoxifen or had tamoxifen stopped at relapse. The data of these patients are shown separately. 47 of the 86 fully evaluable patients (55%) had an objective response, which was complete in 25 (29%). The dominant metastatic type and the number of involved sites were the most important factors influencing response to retreatment. Patients with soft tissue metastases had a high response rate (36/52, 69%) compared with those who had visceral involvement (9/24, 38%) or those with bony disease (2/10, 20%) (P = 0.002). In conclusion, response rates to retreatment with CMF were similar to those expected in a non-pretreated population. The patterns of relapse and the number of metastatic sites were the most important factors predicting response to retreatment, while treatment-free interval (usually longer than 6 months due to the study design) did not influence response rates. This study supports the hypothetic effectiveness of late reintroduction of adjuvant

    Purpose: Two recent randomized, phase III trials in Asia (ACTS-GC and CLASSIC) documented the survival benefit of postoperative chemotherapy after D2 lymph node dissection in patients with gastric cancer. We sought to determine what factors influenced clinicians' choices of either S-1 or capecitabine plus oxaliplatin (CAPOX) as adjuvant therapy after curative D2 gastrectomy. Materials and Methods: We retrospectively reviewed the clinicopathologic factors and adjuvant treatments for 435 patients from nine centers in Korea who were treated with either S-1 or CAPOX adjuvant chemotherapy after undergoing curative D2 gastrectomy between January 2013 and July 2014. Results: Of the 435 patients, 204 (46.9%) were treated with S-1 and 231 (53.1%) were treated with CAPOX. The median age at diagnosis was 61 years (range, 30-88). CAPOX was prescribed more often for patients who were 65 years of age or younger than for patients who were age 65 or older (77.1% vs. 22.9%, P<0.0001). Of the patients in stage II, 121 (60.8%) were treated with S-1 and 78 (39.2%) were given CAPOX; however, of those in stage III, 83 (35.2%) received S-1 and 153 (64.8%) were treated with CAPOX (P<0.0001). Conclusions: Clinicians only preferred CAPOX for younger patients with stage III gastric cancer after curative D2 gastrectomy. However, for elderly patients, clinicians more chose S-1 regardless of the stage.

    The solitary fibrous tumor of central nervous system is rare. Herein, a case of solitary fibrous tumor arising from sellar region is described. A 60-year-old man underwent subtotal excision of the tumor because of extensive infiltration of optical and vascular structures. In view of the presence of residual tumor, he was treated with adjuvant radiation therapy. After a follow-up period of 1 year, there was no progression of the lesion evident on magnetic resonance imaging of the brain. Solitary fibrous tumor should be considered as one of the differential diagnosis of a mass lesion arising in sellar region. Immunohistochemistry with CD34 is valuable for discerning the diagnosis. Complete surgery should be the goal of treatment and adjuvant radiation therapy may be considered for residual or recurrent disease.

    Health-related quality of life (HRQOL), symptoms of depression, and adverse events (AEs) were compared between Japanese postmenopausal patients with hormone-sensitive breast cancer (BC) who received adjuvant tamoxifen, exemestane, or anastrozole in an open-labeled, randomized, multicenter trial designated as the National Surgical Adjuvant Study of Breast Cancer (N-SAS BC) 04 substudy of the Tamoxifen Exemestane Adjuvant Multinational (TEAM) trial. During the first year of treatment, HRQOL and symptoms of depression were analyzed using the Functional Assessment of Cancer Therapy-Breast (FACT-B) and its Endocrine Symptom Subscale (ES), and the Center for Epidemiologic Studies Depression Scale (CES-D), respectively. In addition, predefined AEs were analyzed. A total of 166 eligible patients were randomly assigned to receive adjuvant tamoxifen, exemestane, or anastrozole. FACT-B scores increased after treatment began and remained significantly higher in the tamoxifen group than in the exemestane group or anastrozole group during the first year (P = 0.045). FACT-B scores were similar in the exemestane group and anastrozole group. ES scores and CES-D scores were similar in all treatment groups. Arthralgia and fatigue were less frequent, but vaginal discharge was more frequent in the tamoxifen group than in the exemestane group or anastrozole group. HRQOL was better in Japanese postmenopausal women treated with tamoxifen than those treated with exemestane or anastrozole. HRQOL and AEs were similar with exemestane and anastrozole. Given the results of the TEAM trial, upfront use of tamoxifen followed by an aromatase inhibitor (AI) may be an important option for adjuvant endocrine therapy in Japanese postmenopausal women.

    Despite improvements in adjuvant chemotherapy regimens in breast cancer, personalised use of specific cytotoxic regimens remains a clinical challenge. Defining the correct therapeutic strategy for individual patients with breast cancer based on the genomic and transcriptomic characteristics of the tumour and the patient remains an area of unmet clinical need. Despite the promise of microarray-based predictors of response to chemotherapy, clinical decisions are still guided by a limited constellation of biomarkers. In this review we will address current genomic and transcriptomic approaches to the stratification of adjuvant therapies in breast cancer, the reasons for the limited success in the incorporation of novel multi-gene predictors of response to chemotherapy in clinical practice and focus on new approaches that aim to understand the clonal evolution of the disease. The polygenic nature of drug resistance, and inter- and intra-tumour heterogeneity are considered as important research areas, given that they may constitute important challenges for the development of chemotherapy-specific response predictors.

    The Lung Adjuvant Cisplatin Evaluation (LACE) meta-analysis and the meta-analysis of individual participant data reported by non-small cell lung cancer (NSCLC) Meta-analysis Collaborative Group in neo-adjuvant setting validated respectively that adjuvant and neoadjuvant chemotherapy would significantly improve overall survival (OS) and recurrence-free survival for resectable NSCLC. However, chemotherapy has reached a therapeutic plateau. It has been confirmed that epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) targeting therapy provides a dramatic response to patients with advanced EGFR-mutation positive NSCLC. Researchers have paid more attention to exploring applications of TKIs to early resectable NSCLCs. Several studies on adjuvant TKI treatment concluded its safety and feasibility. But there existed certain limitations of these studies as inference factors to interpret data accurately: the BR19 study recruited patients among which almost 52% had stage IB and only 15 (3.0%, 15/503) had been confirmed with EGFR-mutant type; retrospective studies performed at Memorial Sloan Kettering Cancer Center (MSKCC) selected EGFR mutant-type NSCLC patients but couldn’t avoid inherent defects inside retrospective researches; the RADIANT study revised endpoints from targeting at EGFR immunohistochemistry (IHC)+ and/or fluorescence in situ hybridization (FISH)+ mutation to only EGFR IHC+ mutation, leading to selective bias; despite that the SELECT study validated efficacy of adjuvant TKI and second round of TKI after resistance occurred, a single-arm clinical trial is not that persuasive in the absence of comparison with chemotherapy. Taking all these limitations into account, CTONG1104 in China and IMPACT in Japan have been conducted and recruiting patients to offer higher level of evidences to explore efficacy of preoperative TKI therapy for early resectable EGFR mutation positive NSCLC patients (confirmed by pathological results of tumor tissue or

    Purpose: To compare the survival impact of adjuvant external beam radiation therapy (RT) for malignant gliomas of glioblastoma (GBM), anaplastic astrocytoma (AA), anaplastic oligodendroglioma (AO), and mixed anaplastic oligoastrocytoma (AOA) histology. Methods and Materials: The Surveillance, Epidemiology, and End Results (SEER) database was queried from 1998 to 2007 for patients aged ≥18 years with high-grade gliomas managed with upfront surgical resection, treated with and without adjuvant RT. Results: The primary analysis totaled 14,461 patients, with 12,115 cases of GBM (83.8%), 1312 AA (9.1%), 718 AO (4.9%), and 316 AOA (2.2%). On univariate analyses, adjuvant RT was associated with significantly improved overall survival (OS) for GBMs (2-year OS, 17% vs 7%, p<.001), AAs (5-year OS, 38% vs 24%, p<.001), and AOAs (5-year OS, 55% vs 44%, p=.026). No significant differences in OS were observed for AOs (5-year OS, with RT 50% vs 56% without RT, p=.277). In multivariate Cox proportional hazards models accounting for extent of resection, age, sex, race, year, marital status, and tumor registry, RT was associated with significantly improved OS for both GBMs (HR, 0.52; 95% CI, 0.50-0.55; P<.001) and AAs (HR, 0.57; 95% CI, 0.48-0.68; P<.001) but only a trend toward improved OS for AOAs (HR, 0.70; 95% CI, 0.45-1.09; P=.110). Due to the observation of nonproportional hazards, Cox regressions were not performed for AOs. A significant interaction was observed between the survival impact of RT and histology overall (interaction P<.001) and in a model limited to the anaplastic (WHO grade 3) histologies. (interaction P=.024), characterizing histology as a significant predictive factor for the impact of RT. Subgroup analyses demonstrated greater hazard reductions with RT among patients older than median age for both GBMs and AAs (all interaction P≤.001). No significant interactions were observed between RT and extent of resection. Identical patterns of significance were

    Introduction: When cancer patients have advanced disease and a primary cure is no longer possible, the focus is on maintaining the patientʼs quality of life. Recent therapeutic advances in breast cancer treatment mean that even patients with metastatic disease can remain stable for long periods of time. The aim of this study was to look at the health-related quality of life (HRQL) of these patients and compare it with data for the general population and to show the differences in outcomes for different survey instruments used to measure quality of life. Material and Methods: A total of 96 breast cancer patients with metastatic disesae or receiving adjuvant therapy were questioned about their quality of life. Patients were investigated using the established survey instruments EORTC QLQ-C30, EORTC QLQ-BR23, EQ-5D-5L and EQ VAS. All patients filled out questionnaires. Statistical analysis was done using MS Excel and SPSS. Results: Although the questionnaires were completed at the same time, the different questionnaires showed significant differences with regard to the level of stress experienced by the patient. When the EQ VAS questionnaire was used, the patientʼs current state of health was assessed as significantly better than with the EORTC QLQ-C30. Overall, all aspects of patientsʼ quality of life were found to be in need of optimization and HRQL of patients was significantly poorer in all areas compared to the reference population. Conclusion: To improve the quality of life of patients with metastatic disease, it is necessary to continuously monitor the success of therapy. The choice of survey tools is highly relevant as assessments differ considerably depending on the choice of questionnaire. PMID:27761027

    Adjuvant chemotherapy with fluorouracil (FU) and levamisole or FU/leucovorin (LV) has been established as effective adjuvant treatment for patients with stage III colon cancer. Among several other promising treatment strategies in resected colon cancer, intraperitoneal anti-cancer drug administration with its appealing rationale of counteracting microscopic residual disease on peritoneal surfaces and occult metachronous liver metastases by achieving high intraportal drug concentrations has not yet undergone sufficient clinical evaluation. To determine whether a combination of this locoregional therapeutic concept with systemic intravenous administration of FU/LV would yield better results than conventional adjuvant chemoimmunotherapy with FU/levamisole, the present randomized study was initiated. A total of 241 patients with resected stage III or high-risk stage II (T4N0M0) colon cancer were randomly assigned to 'standard therapy' with FU and levamisole, given for a duration of 6 months, or to an investigational arm, consisting of LV 200 mg m(-2) plus FU 350 mg m(-2), both administered intravenously (days 1-4) and intraperitoneally (days 1 and 3) every 4 weeks for a total of six courses. In patients with stage II disease, no significant difference was noted between the two arms after a median follow-up time of 4 years (range 2.5-6 years). Among 196 eligible patients with stage III disease, however, a comparative analysis of the two treatment groups suggested both an improvement in disease-free survival (P = 0.0014) and a survival advantage (P = 0.0005), with an estimated 43% reduction in mortality rate (95% confidence interval 26-70%) in favour of the investigational arm. In agreement with its theoretical rationale, combined intraperitoneal and intravenous FU/LV was particularly effective in reducing locoregional tumour recurrences with or without liver or other organ site involvement (9 vs 25 patients in the FU/levamisole arm; P = 0.005).

    Background: Breast cancer (BC) is the leading cause of cancer death in Chilean women. Adjuvant chemotherapy decreases recurrence and death from BC. The recommendation to indicate chemotherapy is complex. Adjuvant! Online is a valuable computational tool to predict survival benefit obtained with adjuvant systemic therapy. Previous studies in Caucasian patients with BC showed that they are willing to receive chemotherapy for a small benefit. No studies, to our knowledge, have been done in the Hispanic or Latino populations. Methods: We interviewed females with BC who had previously received adjuvant chemotherapy. Age, stage at presentation, time since last chemotherapy, type of chemotherapy, marital status, number of children, and level of education were recorded. We used the graphic representation from Adjuvant! Online to question each patient on how much survival benefit she required to accept chemotherapy. Results: There were 101 women surveyed. The average age was 55.9 (±10.2), 54.5% had involved lymph nodes, 59.4% were married, and 15.8% did not have parity; 62.3% of females accepted chemotherapy for an absolute survival benefit of 1% or less. In a multivariate analysis, younger (p = 0.02) and less-educated patients (p = 0.018) were associated with lower survival benefit required to opt for chemotherapy. Conclusion: In our study, the acceptance of chemotherapy by the Hispanic population requires minimal survival benefit and is in agreement with the Caucasian population reported elsewhere. To our knowledge, our report is the first study that evaluates the perception of Latino patients regarding the benefit of chemotherapy in early BC. PMID:24678346

    Safinamide (SAF) is a new drug developed for the treatment of Parkinson's disease (PD). It is a benzylamino derivative with multiple mechanisms of action and antiparkinsonian, anticonvulsant, and neuroprotective properties. SAF inhibits monoamine oxidase B and dopamine reuptake and glutamate release, blocks voltage-dependent sodium channels, and modulates calcium channels. Although the antiparkinsonian effect can be ascribed in part to the inhibition of the monoamine oxidase B, which is complete at 50 mg, the enhanced benefit seen at the 100 mg dose is probably due to nondopaminergic mechanisms. SAF will represent an important option for patients with both early and advanced PD. In early PD patients, the addition of SAF to dopamine agonists may be an effective treatment strategy to improve motor function, prolong the use of dopamine agonists, and/or delay the introduction of levodopa. In advanced parkinsonian patients, SAF has been demonstrated to significantly increase on time with no, or nontroublesome dyskinesias. All studies performed have demonstrated its efficacy in benefiting both short-term and long-term quality-of-life outcomes in both early and advanced PD patients. SAF has been investigated in long-term (24 months), double-blind, placebo-controlled studies, where it showed a very good safety profile. SAF has not been studied in de novo PD patients, and its potential positive effect on dyskinesia deserves further dedicated studies. PMID:26917951

    Patients are increasingly involved in cancer treatment decisions and yet little research has explored factors that may affect patient attitudes and beliefs about their therapeutic choices. This paper examines psychosocial factors (e.g., attitudes, social support), provider-related factors (e.g., communication, trust), and treatment considerations in a prospective study of a sample of non-metastatic breast cancer patients eligible for chemotherapy and/or hormonal therapy (BQUAL cohort). The data come from a multisite cohort study of white, black, Hispanic, and Asian non-metastatic breast cancer patients recruited in New York City, Northern California, and Detroit, Michigan. Baseline surveys were conducted over the telephone between 2006 and 2010 among a total of 1,145 women. Most participants were white (69 %), had more than a high school education (76 %), and were diagnosed with stage I disease (51 %). The majority of women reported discussing chemotherapy and hormonal therapy with their doctor (90 and 83 %, respectively); these discussions primarily took place with medical oncologists. Nearly a quarter of women reported that the treatment decision was difficult, and the majority were accompanied to the doctor (76 %) and involved a friend or family member in making the decision (54 %). Positive considerations (e.g., beliefs about treatment reducing risk of recurrence) were important in making treatment decisions. Participants preferred a shared decision-making style, but results suggested that there is room for improvement in terms of actual patient's involvement in making the decision and provider communication, particularly among black patients. Patients 65 years and older reported fewer provider discussions of chemotherapy, poorer patient-provider communication, higher rates of being assisted by family members in making the decision, and more negative attitudes and beliefs toward treatment.

    Cosmesis and complication rates were examined in patients with early stage carcinoma of the breast treated by biopsy and radiation therapy with and without adjuvant chemotherapy in an attempt to determine the effect of chemotherapy upon these parameters. Between April 1, l975 and June 1, 1980, 51 patients were treated with radiation therapy and adjuvant chemotherapy (XRT + ACT) and 83 patients with radiotherapy alone (XRT). Cosmetic results deteriorated with time in both groups but to a greater extent in the XRT + ACT group. Comparison of the two treatment groups revealed that complication rates were significantly incresed in the XRT + ACT group. Of the 51 patients in the XRT + ACT group, 21 patients (41%) suffered complications compared to 8 (10%) of the 83 patients in the XRT group. This difference in complication rates resulted primarily from an increased incidence in the XRT + ACT group of wet desquamation in the electron beam portal used to treat the internal mammary lymph nodes and a trend towards a higher incidence of spontaneous nonpathologic rib fractures, myositis and arm edema. The authors' preliminary conclusions are that adjuvant chemotherapy has a negative impact upon cosmesis and complications rates in patients being treated with definitive radiotherapy. However, cosmetic results remain satisfactory and complication rates are maintained at an acceptable level.

    Background: The International Breast Cancer Study Group Trial VIII compared long-term efficacy of endocrine therapy (goserelin), chemotherapy [cyclophosphamide, methotrexate and fluorouracil (CMF)], and chemoendocrine therapy (CMF followed by goserelin) for pre/perimenopausal women with lymph-node-negative breast cancer. Patients and methods: From 1990 to 1999, 1063 patients were randomized to receive (i) goserelin for 24 months (n = 346), (ii) six courses of ‘classical’ CMF (cyclophosphamide, methotrexate, 5-fluorouracil) chemotherapy (n = 360), or (iii) six courses of CMF plus 18 months goserelin (CMF→ goserelin; n = 357). Tumors were classified as estrogen receptor (ER) negative (19%), ER positive (80%), or ER unknown (1%); 19% of patients were younger than 40. Median follow-up was 12.1 years. Results: For the ER-positive cohort, sequential therapy provided a statistically significant benefit in disease-free survival (DFS) (12-year DFS = 77%) compared with CMF alone (69%) and goserelin alone (68%) (P = 0.04 for each comparison), due largely to the effect in younger patients. Patients with ER-negative tumors whose treatment included CMF had similar DFS (12-year DFS CMF = 67%; 12-year DFS CMF→ goserelin = 69%) compared with goserelin alone (12-year DFS = 61%, P= NS). Conclusions: For pre/perimenopausal women with lymph-node-negative ER-positive breast cancer, CMF followed by goserelin improved DFS in comparison with either modality alone. The improvement was the most pronounced in those aged below 40, suggesting an endocrine effect of prolonged CMF-induced amenorrhea. PMID:21325445

    Objective Chinese herbal products (CHPs) are widely used for atrial fibrillation (AF) in Taiwan. We investigated the effect of adjuvant CHPs in preventing ischemic stroke in patients with AF. Methods Taiwanese patients in the Health Insurance Database newly diagnosed with AF during 2000–2011 were enrolled. Medication treatment with/without CHPs was administered within 7 days after the AF diagnosis. The clinical endpoint was an ischemic stroke. The Chi-square test, Fisher’s exact test, and Student t test were used to examine differences between the traditional Chinese medicine (TCM) and non-TCM cohorts. Cox proportional hazard regression was used to assess the risk for ischemic stroke between two cohorts. Results Three hundred and eleven patients underwent TCM treatment and 1715 patients did not. Compared to non-TCM users, TCM users had a lower incidence of stroke (12.59% vs. 1.93%, respectively) and lower risk of stroke [CHA2DS2-VASc score = 0–2 (hazard ratio = 0.20; 95% confidence interval = 0.06–0.65)]. Compared to non-TCM users, the stroke risk was significantly lower in TCM users with AF who were female or younger than 65 years, but not in males, people more than 65 years old, or people with comorbidities. Compared to TCM users, non-TCM users who received conventional treatment had a higher ischemic stroke risk. The risk for AF-related hospitalization was significantly lower in TCM users (0.64%) than in non-TCM users (38.1%). Conclusions Users of TCM with AF have a lower risk of new-onset ischemic stroke.

    Chemotherapy is the only evidence based adjuvant systemic treatment option in triple negative breast cancer (TNBC). Despite emerging results for targeted biological therapies for this subpopulation, lack of robust results does not currently support their use beyond the confines of a clinical trial. Conventional systemic chemotherapy remains the standard of care and is curative in a minority of patients. There is no defined standard chemotherapy and there is currently no robust, prospective, randomized data to advise different use of specific chemotherapy agents in TNBC as compared to non-TNBC. Data suggest high sensitivity to chemotherapy, however it is yet to be determined whether this increased sensitivity is agent/regimen specific or whether it reflects general chemosensitivity. This review will focus on systemic chemotherapy in early TNBC, particularly anthracyclines and platinums, and potential predictive tools to guide chemotherapy use. PMID:22015281

    Propolis is a bee-metabolized resinous substance (bee glue) from plant sap and gums. It has been in usage as a healing agent since antiquity, yet has not garnered global popularity as a health promoter. Its biological effects, which range from antimicrobial, antioxidant, anti-inflammatory, antidiabetic, dermatoprotective, anti-allergic, laxative and immunomodulatory to anticancer, have been validated. Propolis has shown efficacy against brain, head and neck, skin, breast, liver, pancreas, kidney, bladder, prostate, colon and blood cancers. The inhibition of matrix metalloproteinases, anti-angiogenesis, prevention of metastasis, cell-cycle arrest, induction of apoptosis and moderation of the chemotherapy-induced deleterious side effects have been deduced as the key mechanisms of cancer manipulation. The components conferring antitumor potentials have been identified as caffeic acid phenethyl ester, chrysin, artepillin C, nemorosone, galangin, cardanol, etc. These compounds target various genetic and biochemical pathways of cancer progression. Depending on the botanical sources and the geographical origin, biological activities of propolis vary. Despite phenomenal development in cancer research, conventional therapy falls short in complete malignancy management. The findings obtained so far build hope that propolis as a complementary medicine may address the lacunae. This review documents the recent advances and scope of amendement in cancer remediation with adequate emphasis on the mechanistic aspect of propolis.

    Purpose: To evaluate the safety and feasibility of concurrent radiation therapy and paclitaxel-based adjuvant chemotherapy, given either weekly or every 3 weeks, after adjuvant doxorubicin and cyclophosphamide (AC). Methods and Materials: After definitive breast surgery and AC chemotherapy, 40 patients with operable Stage II or III breast cancer received protocol-based treatment with concurrent paclitaxel and radiation therapy. Paclitaxel was evaluated on 2 schedules, with treatment given either weekly x 12 weeks (60 mg/m{sup 2}), or every 3 weeks x 4 cycles (135-175 mg/m{sup 2}). Radiation fields and schedules were determined by the patient's surgery and pathology. The tolerability of concurrent therapy was evaluated in cohorts of 8 patients as a phase I study. Results: Weekly paclitaxel treatment at 60 mg/m{sup 2} per week with concurrent radiation led to dose-limiting toxicity in 4 of 16 patients (25%), including 3 who developed pneumonitis (either Grade 2 [1 patient] or Grade 3 [2 patients]) requiring steroids. Efforts to eliminate this toxicity in combination with weekly paclitaxel through treatment scheduling and CT-based radiotherapy simulation were not successful. By contrast, dose-limiting toxicity was not encountered among patients receiving concurrent radiation with paclitaxel given every 3 weeks at 135-175 mg/m{sup 2}. However, Grade 2 radiation pneumonitis not requiring steroid therapy was seen in 2 of 24 patients (8%) treated in such a fashion. Excessive radiation dermatitis was not observed with either paclitaxel schedule. Conclusions: Concurrent treatment with weekly paclitaxel and radiation therapy is not feasible after adjuvant AC chemotherapy for early-stage breast cancer. Concurrent treatment using a less frequent paclitaxel dosing schedule may be possible, but caution is warranted in light of the apparent possibility of pulmonary injury.

    Amputation and chemotherapy are the mainstay of treatment for canine appendicular osteosarcoma (OSA). In vitro studies have demonstrated anti-tumour activity of pamidronate against canine OSA. The purpose of this study was to assess the safety of adding pamidronate to standard post-operative carboplatin chemotherapy in 17 dogs with appendicular OSA treated with limb amputation. Median disease-free interval (DFI) and median survival time (MST) were evaluated as secondary endpoints. Incidence of side effects and treatment outcomes were compared to 14 contemporary control patients treated with carboplatin alone. There were no identified side effects to the pamidronate treatment. The median DFI for the study group was 185 days compared to 172 days for the control group (P = 0.90). The MST of the study group was 311 days compared to 294 days for the control group (P = 0.89). Addition of pamidronate to carboplatin chemotherapy for the treatment of canine appendicular OSA is safe and does not impair efficacy of standard carboplatin treatment.

    Introduction In 2010, national guidelines recommended that women with nonmetastatic, hormone receptor–positive breast cancer take adjuvant hormone therapy for 5 years. As results from randomized clinical trials became available, guidelines were revised in 2014 to recommend 10 years of therapy. Despite evidence of its efficacy, low initiation rates have been documented among women insured by New York State Medicaid. This article describes a coordinated quality improvement pilot conducted by a state department of health and Medicaid managed care plans to engage women in guideline-concordant adjuvant hormone therapy. Methods Women enrolled in Medicaid managed care with nonmetastatic, hormone receptor–positive breast cancer and who had surgery from May 1, 2012, through November 30, 2012, were identified using linked Medicaid and Cancer Registry data. Adjuvant hormone therapy status was determined from Medicaid pharmacy data. Contact information for nonadherent women was supplied to health plan care managers who conducted outreach activities. Adjuvant hormone therapy status in the 6 months following outreach was evaluated. Results In the 6 months postoutreach, 61% of women in the contacted group filled at least 1 prescription, compared with 52% in the noncontacted group. Among those with at least 1 filled prescription, 50% of the contacted group were adherent, compared with 25% in the noncontacted group. Conclusion This pilot suggests outreach conducted by health plan care managers, facilitated by linked Medicaid and Cancer Registry data, is an effective method to improve adjuvant hormone therapy initiation and adherence rates in Medicaid managed care–insured women.

    Purpose/Objective(s): To determine the impact of adjuvant radiation treatment (RT) on recurrence-free survival (RFS), disease-specific survival (DSS), and overall survival (OS) in patients with high-risk 2009 International Federation of Gynecology and Obstetrics stage I-II endometrial carcinoma. Methods and Materials: We identified 382 patients with high-risk EC who underwent hysterectomy. RFS, DSS, and OS were calculated from the date of hysterectomy by use of the Kaplan-Meier method. Cox regression modeling was used to explore the risks associated with various factors on survival endpoints. Results: The median follow-up time for the study cohort was 5.4 years. The median age was 71 years. All patients underwent hysterectomy and salpingo-oophorectomy, 93% had peritoneal cytology, and 85% underwent lymphadenectomy. Patients with endometrioid histology constituted 72% of the study cohort, serous in 16%, clear cell in 7%, and mixed histology in 4%. Twenty-three percent of patients had stage II disease. Adjuvant management included RT alone in 220 patients (57%), chemotherapy alone in 25 patients (7%), and chemoradiation therapy in 27 patients (7%); 110 patients (29%) were treated with close surveillance. The 5-year RFS, DSS, and OS were 76%, 88%, and 73%, respectively. On multivariate analysis, adjuvant RT was a significant predictor of RFS (P<.001) DSS (P<.001), and OS (P=.017). Lymphovascular space involvement was a significant predictor of RFS and DSS (P<.001). High tumor grade was a significant predictor for RFS (P=.038) and DSS (P=.025). Involvement of the lower uterine segment was also a predictor of RFS (P=.049). Age at diagnosis and lymphovascular space involvement were significant predictors of OS: P<.001 and P=.002, respectively. Conclusion: In the treatment of patients with high-risk features, our study suggests that adjuvant RT significantly improves recurrence-free, disease-specific, and overall survival in patients with early-stage endometrial carcinoma

    Stroke commonly results in substantial and persistent deficits in locomotor function. The majority of scientific inquiries have focused on singular intervention approaches, with recent attention given to task specific therapies. We propose that measurement should indicate the most critical limiting factor(s) to be addressed and that a combination of adjuvant treatments individualized to target accompanying impairment(s) will result in the greatest improvements in locomotor function. We explore training to improve walking performance by addressing a combination of: (1) walking specific motor control; (2) dynamic balance; (3) cardiorespiratory fitness and (4) muscle strength and put forward a theoretical framework to maximize the functional benefits of these strategies as physical adjuvants. The extent to which any of these impairments contribute to locomotor dysfunction is dependent on the individual and will undoubtedly change throughout the rehabilitation intervention. Thus, the ability to identify and measure the relative contributions of these elements will allow for identification of a primary intervention as well as prescription of additional adjuvant approaches. Importantly, we highlight the need for future studies as appropriate dosing of each of these elements is contingent on improving the capacity to measure each element and to titrate the contribution of each to optimal walking performance.

    The effect of Photofrin-based photodynamic therapy (PDT) and adjuvant treatment with serum vitamin D3-binding protein-derived macrophage-activating factor (DBPMAF) was examined using a mouse SCCVII tumour model (squamous cell carcinoma). The results show that DBPMAF can markedly enhance the curative effect of PDT. The most effective DBPMAF therapy consisted of a combination of intraperitoneal and peritumoral injections (50 and 0.5 ng kg-1 respectively) administered on days 0, 4, 8 and 12 after PDT. Used with a PDT treatment curative to 25% of the treated tumours, this DBPMAF regimen boosted the cures to 100%. The DBPMAF therapy alone showed no notable effect on the growth of SCCVII tumour. The PDT-induced immunosuppression, assessed by the evaluation of delayed-type contact hypersensitivity response in treated mice, was greatly reduced with the combined DBPMAF treatment. These observations suggest that the activation of macrophages in PDT-treated mice by adjuvant immunotherapy has a synergistic effect on tumour cures. As PDT not only reduces tumour burden but also induces inflammation, it is proposed that recruitment of the activated macrophages to the inflamed tumour lesions is the major factor for the complete eradication of tumours.

    The incidence of second non-breast primary cancer following adjuvant treatment was evaluated using data from patients enrolled from 1978 to 1999 in four International Breast Cancer Study Group (IBCSG) trials. The occurrence of these tumours as sites of first failure was assessed separately for two treatment comparisons: toremifene versus tamoxifen for five years in 1035 patients in IBCSG Trials 12-93 and 14-93 with a median follow-up of eight years and endocrine therapy (toremifene or tamoxifen) versus chemoendocrine therapy (CMF or AC plus toremifene or tamoxifen) in 1731 patients from IBCSG Trials III, VII and 12-93, with a combined median follow-up of 14 years. No significant differences in second non-breast primary tumours were observed in either comparison. In particular the incidences of second primary uterine tumours with toremifene and tamoxifen were similar and no significant increase of secondary leukaemias was observed with chemoendocrine therapy compared with endocrine therapy.

    Background Radiation therapy is a critical component of treatment for thymic tumors. However, radiation-induced toxicity may reduce benefit, particularly in the adjuvant setting. Proton beam therapy (PBT), due to its characteristic Bragg peak, is ideally suited to treat the anterior mediastinum while sparing organs at risk. To date, PBT to treat thymic tumors has only been reported in three single-patient case studies. In this study, we evaluated patterns of failure and toxicity in patients treated for thymoma and thymic carcinoma using PBT and hypothesized that PBT can achieve excellent local control with limited high grade toxicity. Methods All patients with thymoma or thymic carcinoma treated with PBT between 2011–2015 were analyzed. Either double scattered proton therapy (DS-PT) or pencil beam scanning (PBS) were used. Toxicity was assessed using CTCAE v 4.2. Local control, distant control, and overall survival were analyzed by the Kaplan-Meier method from the time of PBT completion. Results Twenty-seven patients were included. Patients were a median age of 56 years, predominantly female (56%), and had thymoma (85%) or thymic carcinoma (15%). They were treated with definitive (22%) or salvage (15%) PBT or adjuvant (63%) PBT following resection with predominantly close (23%) or positive (50%) margins. Forty-one percent also received chemotherapy. Patients were treated to a median of 61.2 Gy (range 50.4–70.2 Gy) using DS-PT (85%) or PBS (15%). Median mean lung dose, volume of lung receiving ≥20 Gy (V20), and V5 were 98 cGy (1–2,050 cGy), 18% (0–38%), and 26.2% (0–55%). Median mean heart and esophagus doses were 1,065 cGy (105–3,356cGy) and 1,072cGy (0–4,655 cGy). No patient experienced grade ≥3 acute or chronic toxicity. Acute grade ≥2 toxicities included fatigue (11%), esophagitis (7%), dermatitis (37%), and pneumonitis in one patient (4%) who received 2 prior thoracic radiotherapy courses. Late grade ≥2 toxicity was limited to a single

    Purpose: To retrospectively evaluate the outcome and toxicity in patients receiving high-dose (>69 Gy) adjuvant radiotherapy (HD-ART) and the impact of androgen deprivation therapy (ADT). Methods and Materials: Between 1999 and 2008, 225 node-negative patients were referred for HD-ART with or without ADT to two large academic institutions. Indications for HD-ART were extracapsular extension, seminal vesicle invasion (SVI), and/or positive surgical margins at radical prostatectomy (RP). A dose of at least 69.1 Gy was prescribed to the prostate bed and seminal vesicle bed. The ADT consisted of a luteinizing hormone-releasing hormone analog. The duration and indication of ADT was left at the discretion of the treating physician. The effect of HD-ART and ADT on biochemical (bRFS) and clinical (cRFS) relapse-free survival was examined through univariate and multivariate analysis, with correction for known patient- and treatment-related variables. Interaction terms were introduced to evaluate effect modification. Results: After a median follow-up time of 5 years, the 7-year bRFS and cRFS were 84% and 88%, respectively. On multivariate analysis, the addition of ADT was independently associated with an improved bRFS (hazard ratio [HR] 0.4, p = 0.02) and cRFS (HR 0.2, p = 0.008). Higher Gleason scores and SVI were associated with decreased bRFS and cRFS. A lymphadenectomy at the time of RP independently improved cRFS (HR 0.09, p = 0.009). The 7-year probability of late Grade 2-3 toxicity was 29% and 5% for genitourinary (GU) and gastrointestinal (GI) symptoms, respectively. The absolute incidence of Grade 3 toxicity was <1% and 10% for GI and GU symptoms, respectively. The study is limited by its retrospective design and the lack of a standardized use of ADT. Conclusions: This retrospective study shows significantly improved bRFS and cRFS rates with the addition of ADT to HD-ART, with low Grade 3 gastrointestinal toxicity and 10% Grade 3 genitourinary toxicity.

    Background Adjuvant zoledronic acid (za) appears to improve disease-free survival (dfs) in women with early-stage breast cancer and low levels of estrogen (lle) because of induced or natural menopause. Characterizing the cost–utility (cu) of this therapy could help to determine its role in clinical practice. Methods Using the perspective of the Canadian health care system, we examined the cu of adjuvant endocrine therapy with or without za in women with early-stage endocrine-sensitive breast cancer and lle. A Markov model was used to compute the cumulative costs in Canadian dollars and the quality-adjusted life-years (qalys) gained from each adjuvant strategy, discounted at a rate of 5% annually. The model incorporated the dfs and fracture benefits of adjuvant za. Probabilistic and one-way sensitivity analyses were conducted to examine key model parameters. Results Compared with a no-za strategy, adjuvant za in the induced and natural menopause groups was associated with, respectively, $7,825 and $7,789 in incremental costs and 0.46 and 0.34 in qaly gains for cu ratios of $17,007 and $23,093 per qaly gained. In one-way sensitivity analyses, the results were most sensitive to changes in the za dfs benefit. Probabilistic sensitivity analysis suggested a 100% probability of adjuvant za being a cost-effective strategy at a threshold of $100,000 per qaly gained. Conclusions Based on available data, adjuvant za appears to be a cost-effective strategy in women with endocrine-sensitive breast cancer and lle, having cu ratios well below accepted thresholds.

    Few predictive markers exist for response to adjuvant chemotherapy in breast cancer. The 78-kD glucose-regulated protein (GRP78) is a potent anti-apoptotic factor, conferring drug resistance. Recently, we reported that high GRP78 expression in breast cancer specimens predict a shorter recurrence-free survival in patients who received doxorubicin-based adjuvant chemotherapy. Interestingly, the opposite effect was observed in 25 patients who additionally received a taxane. To confirm this potentially paradigm shifting finding, we investigated whether GRP78 is associated with recurrence-free survival in an independent cohort of taxane-treated breast cancer patients. Immunohistochemical staining of GRP78 was performed on archival paraffin-embedded formalin-fixed tumor specimens obtained from 48 female breast cancer patients before chemotherapy treatment. These patients received doxorubicin and cyclophosphamide, followed by paclitaxel or docetaxel on a clinical trial. GRP78 expression level was evaluated by a pathologist, masked to all clinical and outcome data. Association between GRP78 expression and recurrence-free survival was evaluated. GRP78 positivity predicts a better recurrence-free survival, independent of other prognostic factors [hazard ratio (HR) for moderate positivity: 0.40 (95% confidence interval (CI): 0.087–1.83); HR for strong positivity: 0.16 (95% CI: 0.018–1.50); Ptrend=0.053]. In a pooled analysis with the previous 25 patients, almost identical HRs were obtained with Ptrend=0.024. This provides further evidence that GRP78 is a potential independent predictor for response to taxane-based adjuvant chemotherapy in breast cancer. PMID:20473863

    During a two year period, 65 patients with Stage II non-seminomatous testis cancer were randomized to receive adjuvant chemotherapy and radiation. Of the 52 evaluable patients, 23 received radiation followed by chemotherapy (sequential), and 29 received the same chemotherapy as initial treatment, but had drug treatment temporarily interrupted for radiation (sandwich). The combined treatment was well tolerated, but did not eliminate recurrence. With regard to duration of survival and disease-free survival, no statistically significant difference could be found between the sequential and sandwich approaches.

    The aim of this study was to compare the outcome of chemotherapy or radiation as adjuvant therapy for patients with FIGO stage IB-IIA cervical cancer and surgically confirmed intermediate risk factors. Data were collected from patients with uterine cervical cancer FIGO stage IB-IIA who had adjuvant chemotherapy following radical hysterectomy with pelvic lymph node dissection (RHLND, cases) or adjuvant radiotherapy following RHLND (controls). The study groups consisted of 38 cases and 42 controls. Adjuvant treatment was given to the patients with a combination of intermediate risk factors including deep stromal invasion (>50%), lymphvascular space invasion, large tumor size (3-6 cm), or close vaginal resection margin (<1 cm). Comparison of the cases with the controls revealed no significant differences in variables studied including median age (P = 0.18), stage distribution (P = 0.30), histologic subtype (P = 0.93), pathologic tumor size (P = 0.46), depth of the stromal invasion (P = 0.29), lymphvascular space invasion (P = 0.50), and close vaginal resection margin (P = 0.62). The difference in disease-free survival rates was not significant (P = 0.68). However, the overall survival analysis was incomplete due to the limited number of events available at the end of the study period. The findings of this study suggest that adjuvant chemotherapy in patients with FIGO stage IB-IIA uterine cervical cancer and surgically confirmed intermediate risk factors may be effective.

    To prevent probable occult metastatic liver cancer from progressing to clinical disease, the author used internal radiation therapy as an effective adjuvant to surgical excision of primary Dukes' C colonic cancer. A calculated radiation dose of 5000 rads was delivered to the liver by injecting radioactive 32-P chromic phosphate colloid through the superior mesenteric and celiac arteries. When this was done, the colloid passed through the intestines and was mixed thoroughly with the blood and delivered to the liver by the portal vein. The Kupffer cells in the liver trapped the colloid, and a minimum amount passed through the liver and got into the general circulation. This kept the amount of colloid deposited in the bone marrow to a minimum. In a phase-I pilot study in which nine patients were treated, no serious side effects were noted. In eight patients, the liver has remained free of cancer for more than 1 year.

    Cancer survivors are exposed to several risk factors for cognitive dysfunction, such as general anesthesia, surgical trauma, and adjuvant therapies. In our recent study we showed that thalamic volume reduction and attentional dysfunction occurred shortly after surgery. Here, we examined the 6-month prognosis of the 20 patients with breast cancer who underwent surgery. Seven patients did not receive any adjuvant therapy after the surgery and 13 patients received a hormonal therapy after the surgery. We assessed their attentional functions, and thalamic volumes shortly after and 6 months after surgery. We found a significant group x time interaction in the attentional functions (p = 0.033) and the right thalamus (p <  0.05, small volume correction), suggesting the thalamic volume reduction and attentional dysfunction recovered in patients without adjuvant therapy. Our findings provide a better understanding of the potential role of hormonal therapy in relation to the cognitive dysfunction of cancer survivors. PMID:27708377

    Tamoxifen is an unlikely pioneering medicine in medical oncology. Nevertheless, the medicine has continued to surprise us, perform and save lives for the past 40 years. Unlike any other medicine in oncology, it is used to treat all stages of breast cancer, ductal carcinoma in situ, male breast cancer, pioneered the use of chemoprevention by reducing the incidence of breast cancer in women at high risk and induces ovulation in subfertile women! The impact of tamoxifen is ubiquitous. However, the power to save lives from this unlikely success story came from the first laboratory studies which defined that “longer was going to be better” when tamoxifen was being considered as an adjuvant therapy (Jordan 1978 Use of the DMBA-induced rat mammary carcinoma system for the evaluation of tamoxifen as a potential adjuvant therapy Reviews in Endocrine Related Cancer. October Supplement: 49–55.). This is that success story, with a focus on the interdependent components of: excellence in drug discovery, investment in self-selecting young investigators, a conversation with Nature, a conversation between the laboratory and the clinic, and the creation of the Oxford Overview Analysis. Each of these factors was essential to propel the progress of tamoxifen to evolve as an essential part of the fabric of society. “Science is adventure, discovery, new horizons, insight into our world, a means of predicting the future and enormous power to help others”(Hoagland 1990).- Mahlon Hoagland, MD.

    Two first analyses of our clinical trial on TIL as adjuvant therapy for melanoma were published in 2002 and 2007. We present here an update of the clinical results after a 17-year median followup. In this trial, disease-free patients were randomly assigned to receive either TIL/IL-2 or IL-2. The relapse-free survival (RFS) was the primary objective. Eighty-eight patients were enrolled. A new analysis performed in May 2013 did not show significant changes in RFS or OS duration. However, our first finding on the association between the number of invaded lymph nodes and TIL effectiveness was strengthened. The Cox model adjusted on this interaction showed for the first time a significant treatment effect when considering the overall population, both on the RFS and OS. Patients treated with TIL had a longer RFS (P = 0.023) or OS (P = 0.020). This study being with a very long followup (17 years), confirmed the association between TIL effectiveness and the number of invaded lymph nodes, indicating that a low tumor burden could be a crucial factor enhancing the curative effect of TIL in possible microscopic residual disease. Moreover, we confirmed that a prolonged survival was associated with the presence of specific TIL and a decrease in Foxp3 expression. PMID:24741578

Increased efficacy without increased toxicity is expected for combination therapy of rheumatoid arthritis (RA). The aim of the study was to examine the effect of N-feruloylserotonin (N-f-5HT) and methotrexate (MTX) in monotherapy and in combination therapy on disease progression and inflammation in arthritic rats. Adjuvant arthritis was induced by intradermal injection of Mycobacterium butyricum in incomplete Freund's adjuvant in Lewis rats. The experiment included healthy animals, arthritic animals without any drug administration, arthritic animals with administration of N-f-5HT in the oral daily dose of 15 mg/kg b.w., arthritic animals with administration of MTX in the oral dose of 0.3 mg/kg b.w. twice a week and arthritic animals treated with the combination of N-f-5HT and MTX. N-f-5HT in monotherapy reduced only activation of NF-κB and did not have any significant effect on other parameters monitored. Low-dose treatment of MTX decreased the level of IL-1β and MCP-1 on day 14 and activation of NF-κB in liver without significant effect on other parameters. N-f-5HT and MTX combination showed both the anti-arthritic (hind paw volume and arthritic score) and anti-inflammatory effect (plasmatic levels of IL-1β, IL-17, MCP-1, CRP, and activation of NF-κB in liver). In combination with MTX, N-f-5HT markedly potentiated the therapeutic effect of MTX low dose, which resulted in significant improvement of all parameters measured. The findings showed that the combination therapy simultaneously decreased multiple markers of inflammation, a result crucial for future therapy of RA.

    Melanoma patients with regional metastatic disease are at high risk for recurrence and metastatic disease, despite radical lymph node dissection (RLND). We investigated the immunologic response and clinical outcome to adjuvant dendritic cell (DC) vaccination in melanoma patients with regional metastatic disease who underwent RLND with curative intent. In this retrospective study, 78 melanoma patients with regional lymph node metastasis who underwent RLND received autologous DCs loaded with gp100 and tyrosinase and were analyzed for functional tumor-specific T cell responses in skin-test infiltrating lymphocytes. The study shows that adjuvant DC vaccination in melanoma patients with regional lymph node metastasis is safe and induced functional tumor-specific T cell responses in 71% of the patients. The presence of functional tumor-specific T cells was correlated with a better 2-year overall survival (OS) rate. OS was significantly higher after adjuvant DC vaccination compared to 209 matched controls who underwent RLND without adjuvant DC vaccination, 63.6 mo vs. 31.0 mo (p = 0.018; hazard ratio 0.59; 95%CI 0.42–0.84). Five-year survival rate increased from 38% to 53% (p < 0.01). In summary, in melanoma patients with regional metastatic disease, who are at high risk for recurrence and metastatic disease after RLND, adjuvant DC vaccination is well tolerated. It induced functional tumor-specific immune responses in the majority of patients and these were related to clinical outcome. OS was significantly higher compared to matched controls. A randomized clinical trial is needed to prospectively validate the efficacy of DC vaccination in the adjuvant setting. PMID:26942068

    Surgical resection is the gold standard treatment and is considered the only potential cure for cholangiocarcinoma (CCA). However, most of the patients present at a late stage of disease and positive margins are frequently encountered. Therefore, adjuvant therapeutic modalities, such as chemotherapy and/or radiotherapy are needed to improve the survival time of CCA patients. In this study, we analyzed retrospectively the clinical features, overall survival and efficacy with postoperative adjuvant chemotherapy for 171 intrahepatic CCA patients. All those with histologically proved intrahepatic CCA diagnosed during 1998-2002, at Srinagarind Hospital, Faculty of Medicine, Khon Kean University, Thailand, were included in this study. All patients were considered to have resectable tumors with curative intent, 114 patients received postoperative adjuvant chemotherapy with 5-fluorouracil/mitomycin C, of which only 54 patients were given the full 6 cycle treatment. Mass forming type CCA was the major type found in our series. The predictive clinicopathological factors which influenced an unfavorable outcome were tumor size >4 cm, multiple masses, mass forming and periductal gross type, histology with poor differentiation, involvement of serosa, vasculature or diaphragm, advanced tumor stage and positive surgical margin. On the other hand, R0 resection, skeletonization of hepatoduodenal ligaments and complete postoperative adjuvant chemotherapy were predictive of a favorable outcome. Multivariate analysis Cox proportional hazards models revealed that sex, tumor size, serosa involvement, surgical margin status, skeletonization and postoperative adjuvant chemotherapy were independently associated with long term survival post-surgery. Regardless of the surgical margin status, patients who received complete postoperative adjuvant chemotherapy had a significant survival advantage.

    A therapeutic strategy that can eliminate primary tumours, inhibit metastases, and prevent tumour relapses is developed herein by combining adjuvant nanoparticle-based photothermal therapy with checkpoint-blockade immunotherapy. Indocyanine green (ICG), a photothermal agent, and imiquimod (R837), a Toll-like-receptor-7 agonist, are co-encapsulated by poly(lactic-co-glycolic) acid (PLGA). The formed PLGA-ICG-R837 nanoparticles composed purely by three clinically approved components can be used for near-infrared laser-triggered photothermal ablation of primary tumours, generating tumour-associated antigens, which in the presence of R837-containing nanoparticles as the adjuvant can show vaccine-like functions. In combination with the checkpoint-blockade using anti-cytotoxic T-lymphocyte antigen-4 (CTLA4), the generated immunological responses will be able to attack remaining tumour cells in mice, useful in metastasis inhibition, and may potentially be applicable for various types of tumour models. Furthermore, such strategy offers a strong immunological memory effect, which can provide protection against tumour rechallenging post elimination of their initial tumours. PMID:27767031

    Glioblastoma multiforme (GBM) is a CNS (central nervous system) malignancy with a low cure rate. Median time to progression after standard treatment is 7 months and median overall survival is 15 months [1]. Post-treatment vasculogenesis promoted by recruitment of bone marrow derived cells (BMDCs, CD11b+ myelomonocytes) is one of main mechanisms of GBM resistance to initial chemoradiotherapy treatment [2]. Local secretion of SDF-1, cognate ligand of BMDCs CXCR4 receptors attracts BMDCs to the post-radiation tumor site.[3]. This SDF-1 hypoxia-dependent effect can be blocked by AMD3100 (plerixafor) [4]. We report a GBM case treated after chemo- radiotherapy with plerixafor and a combination of an mTOR, a Sirt1 and an EGFRvIII inhibitor. After one year temozolomide and the EGFRvIII inhibitor were stopped. Plerixafor, and the MTOR and Sirt-1 inhibitors were continued. He is in clinical and radiologic remission 30 months from the initiation of his adjuvant treatment. To our knowledge, this is the first report of a patient treated for over two years with a CXCR4 inhibitor (plerixafor), as part of his adjuvant treatment. We believe there is sufficient experimental evidence to consider AMD3100 (plerixafor) part of the adjuvant treatment of GBM. Significance The adjuvant inhibition of GBM vasculogenesis(a process different from local angiogenesis) by specifically blocking the migration of BMDCs to the primary tumor site with inhibitors of the CXCR4/SDF-1 axis represents a potential novel therapeutic approach to GBM. There is significant pre-clinical evidence and validation for its use as demonstrated in a patient derived tumor xenograft model of GBM. Together with other specific anti-tumoral therapies, the active inhibition of vasculogenesis in the adjuvant treatment of GBM is deserving of further exploration. PMID:27489862

    Summary Background Southern Africa has a high incidence of bacterial meningitis in adults, often associated with HIV co-infection. Even with appropriate antibiotic therapy, mortality exceeds 50% and is not improved with corticosteroids. Glycerol adjuvant therapy reduced mortality and long-term morbidity (deafness) in bacterial meningitis in children and is being promoted. If similarly effective in adults, glycerol would provide a cheap, available adjuvant therapy in Africa. Methods Following a dose-finding study, we conducted a randomised double-blind placebo-controlled trial of oral glycerol in adults with bacterial meningitis. Patients with clinical and CSF findings suggestive of bacterial meningitis were randomised either to glycerol or an equivalent volume of sugar solution. The primary outcome was mortality at 40 days with secondary outcomes including disability and mortality restricted to pneumococcal disease. Findings 75ml glycerol QDS was best tolerated and was used for the main study. 265 patients were randomised to receive glycerol or placebo. The trial was stopped early on the advice of the Data and Safety Monitoring Board (DSMB) following a planned interim analysis. Mortality by day 40 was 61/125 (49%) in the placebo and 86/136 (69%) in the glycerol arms, Adjusted Odds Ratio 2·4 (95% CI 1·3-4·2 p0·003). There was no benefit from glycerol for death and disability by day 40 by intention to treat or in predefined subgroups. Two serious adverse events occurred possibly due to study drug. Interpretation Oral glycerol therapy did not improve mortality in adults with bacterial meningitis and cannot be recommended as a suitable adjuvant therapy in resource-poor settings with a high HIV prevalence.

    We present here a nonviral immunogene therapy trial for canine malignant melanoma, an aggressive disease displaying significant clinical and histopathological overlapping with human melanoma. As a surgery adjuvant approach, it comprised the co-injection of lipoplexes bearing herpes simplex virus thymidine kinase and canine interferon-β genes at the time of surgery, combined with the periodic administration of a subcutaneous genetic vaccine composed of tumor extracts and lipoplexes carrying the genes of human interleukin-2 and human granulocyte-macrophage colony-stimulating factor. Following complete surgery (CS), the combined treatment (CT) significantly raised the portion of local disease-free canine patients from 11% to 83% and distant metastases-free (M0) from 44% to 89%, as compared with surgery-only-treated controls (ST). Even after partial surgery (PS), CT better controlled the systemic disease (M0: 82%) than ST (M0: 48%). Moreover, compared with ST, CT caused a significant 7-fold (CS) and 4-fold (PS) rise of overall survival, and >17-fold (CS) and >13-fold (PS) rise of metastasis-free survival. The dramatic increase of PS metastasis-free survival (>1321 days) and CS recurrence- and metastasis-free survival (both >2251 days) demonstrated that CT was shifting a rapidly lethal disease into a chronic one. In conclusion, this surgery adjuvant CT was able of significantly delaying or preventing postsurgical recurrence and distant metastasis, increasing disease-free and overall survival, and maintaining the quality of life. The high number of canine patients involved in CT (301) and the extensive follow-up (>6 years) with minimal or absent toxicity warrant the long-term safety and efficacy of this treatment. This successful clinical outcome justifies attempting a similar scheme for human melanoma.

    Purpose Outcomes for early-stage breast cancer have improved. First-generation adjuvant chemotherapy trials reported a 0.27% 8-year cumulative incidence of myelodysplastic syndrome/acute myelogenous leukemia. Incomplete ascertainment and follow-up may have underestimated subsequent risk of treatment-associated marrow neoplasm (MN). Patients and Methods We examined the MN frequency in 20,063 patients with stage I to III breast cancer treated at US academic centers between 1998 and 2007. Time-to-event analyses were censored at first date of new cancer event, last contact date, or death and considered competing risks. Cumulative incidence, hazard ratios (HRs), and comparisons with Surveillance, Epidemiology, and End Results estimates were obtained. Marrow cytogenetics data were reviewed. Results Fifty patients developed MN (myeloid, n = 42; lymphoid, n = 8) after breast cancer (median follow-up, 5.1 years). Patients who developed MN had similar breast cancer stage distribution, race, and chemotherapy exposure but were older compared with patients who did not develop MN (median age, 59.1 v 53.9 years, respectively; P = .03). Two thirds of patients had complex MN cytogenetics. Risk of MN was significantly increased after surgery plus chemotherapy (HR, 6.8; 95% CI, 1.3 to 36.1) or after all modalities (surgery, chemotherapy, and radiation; HR, 7.6; 95% CI, 1.6 to 35.8), compared with no treatment with chemotherapy. MN rates per 1,000 person-years were 0.16 (surgery), 0.43 (plus radiation), 0.46 (plus chemotherapy), and 0.54 (all three modalities). Cumulative incidence of MN doubled between years 5 and 10 (0.24% to 0.48%); 9% of patients were alive at 10 years. Conclusion In this large early-stage breast cancer cohort, MN risk after radiation and/or adjuvant chemotherapy was low but higher than previously described. Risk continued to increase beyond 5 years. Individual risk of MN must be balanced against the absolute survival benefit of adjuvant chemotherapy. PMID

    Weight gain commonly occurs in breast cancer patients who receive adjuvant chemotherapy. Weight gain may cause psychosocial stress and is associated with patient prognosis and survival. Several factors contributing to weight gain have been identified in Western populations. However, there was lack of information associated with body weight changes following adjuvant chemotherapy in Chinese breast cancer patients. To the best of our knowledge, this is the first such study to be conducted in the Chinese population. A total of 98 patients who received adjuvant chemotherapy following a modified radical mastectomy were included in this study. Their weight was measured prior to the first and following the last cycle of chemotherapy. A weight gain, or loss, of >1 kg following adjuvant chemotherapy was considered to be significant. Cancer stage, treatment modalities, menopausal status and other clinical information were obtained through medical record review. The results revealed that the weight changes ranged from -11 to +9 kg, with a mean value of -0.4±4.4 kg. A total of 66.7% of the patients exhibited weight changes (34.6% gained >1 kg and 32.1% lost weight), whereas 33.3% of the patients maintained a stable weight (P<0.001). Patients aged ≤40 years [odds ratio (OR)=1.429, P=0.028], with a weight of ≥60 kg at diagnosis (OR=2.211, P=0.023), who received ≥4 cycles of chemotherapy (OR=1.591, P=0.039) and a total hormone dose of ≥200 mg (OR=2.75, P=0.013) exhibited a higher risk of weight gain. In conclusion, the body weight changes observed in Chinese breast cancer patient post-adjuvant chemotherapy were different from those observed among Western populations, represented predominantly by weight gain and were reflected by approximately equal percentages of weight gain, stable weight and weight loss.

    Primary radiotherapy as a means of managing stage I and II breast cancer is receiving increasing attention. In a prospectively randomized trial comparing modified radical mastectomy to lumpectomy followed by definitive radiotherapy, we evaluated whether radiotherapy has a deleterious effect on the ability to administer adjuvant doxorubicin and cyclophosphamide to patients with histologically positive axillary lymph nodes. All patients were treated with an identical regimen, and doses were escalated to the same degree until myelosuppression occurred. There were no significant differences in the amount of chemotherapy administered to either treatment group. Patients in both groups received approximately 100% of the predicted dose of doxorubicin and approximately 117% of the predicted dose of cyclophosphamide. At present, we have no evidence that there are differences in recurrence rates as a function of the quantity of drug received, although longer follow-up is required.

    Purpose: To evaluate in a porcine model of acute deep vein thrombosis (DVT) the efficacy of dalteparin and antithrombin with respect to heparin for local adjuvant therapy during selective thrombolysis, and the utility of nitroglycerin and iloprost as heparin supplements. Methods: DVT was induced in both hind limbs using a previously described technique (n = 20). Thirty minutes later, the animal was heparinized (2500 IU IV), and bilateral sequestrated thrombolysis was performed using 8 mg alteplase: both external iliac veins were endoluminally occluded with Swan-Ganz catheters, and a multi-sideport infusion wire coaxially introduced through each catheter and advanced into the ipsilateral popliteal vein. In the control limbs, tissue plasminogen activator (tPA) 8 mg was injected as 0.8-ml boluses at 3-min intervals for 2 hr as a 0.25-mg/ml solution containing heparin 50 IU/ml (n 20). On the contralateral side, heparin was substituted with either dalteparin 50 IU/ml (n = 5) or antithrombin 12.5 IU/ml (n = 5), or supplemented with either nitroglycerin 0.075 mg/ml (n = 5) or iloprost (150 ng/ml) (n = 5). Blood samples were taken at predetermined intervals to measure the activated partial thromboplastin time (aPTT), prothrombin time (PT), and fibrinogen concentration. At autopsy, the thrombus mass in the iliofemoral veins was measured, and the extent of residual thrombosis in the venous tributaries graded at four sites. Results: Bilateral thrombolysis was successfully completed in all animals. The median thrombus mass in the iliofemoral veins after thrombolysis was 0.48 g (range 0.06-1.58 g), 0.95 g (0.59-1.29 g), 0.74 g (0.52-0.96 g), and 0.29 g (0.0-0.77 g) for dalteparin, antithrombin, iloprost, and nitroglycerin respectively, as compared with 0.53 g (0.18-0.88 g) (p = 0.69), 0.97 g (0.46-1.15 g) (p = 0.69), 0.53 g (0.48-1.10 g) (p = 0.69), and 0.18 g (0.13-1.04 g) (p = 0.5) for the respective controls. Likewise, the severity of residual thrombosis in the venous

    Background Standardization of surgical and pathologic techniques is crucial to the interpretation of studies evaluating adjuvant therapies for pancreatic cancer (PC). Methods To assess the degree to which treatment administered prior to enrollment of patients in trials of adjuvant therapy is quality controlled, the operative and pathology reports of patients in American College of Surgeons Oncology Group (ACOSOG) Z5031—a national trial of chemoradiation following pancreaticoduodenectomy (PD)—were rigorously evaluated. We analyzed variables with the potential to influence staging or outcome. Results 80 patients reported to have undergone R0 (75%) or R1 (25%) pylorus-preserving (38%) or standard (62%) PD were evaluated. A search for metastases was documented in 96% of cases. The proximity of the tumor to the superior mesenteric vein was reported in 69%; vein resection was required in 9% and lateral venorrhaphy in 14%. The method of dissection along the superior mesenteric artery (SMA) was described in 68%, being ultrasonic dissection (17%), stapler (24%), and clamp and cut (59%). SMA skeletonization was described in 25%, and absence of disease following resection was documented in 24%. The surgeon reported marking the critical SMA margin in 25%; inking was documented in 65% of cases and evaluation of the SMA margin was reported in 47%. A range of 1–49 lymph nodes was evaluated. Only 34% of pathology reports met College of American Pathologists criteria. Conclusions Trials of adjuvant therapy following PD suffer from a lack of standardization and quality control prior to patient enrollment. These data suggest areas for improvement in the design of multidisciplinary treatment protocols. PMID:20811779

    Objective The purpose of this study was to evaluate the prognosis according to the number of high risk factors in patients with high risk factors after radical hysterectomy and adjuvant chemoradiation therapy for early stage cervical cancer. Methods Clinicopathological variables and clinical outcomes of patients with FIGO (International Federation of Gynecology and Obstetrics) stage IB1 to IIA cervical cancer who had one or more high risk factors after radical hysterectomy and adjuvant chemoradiation therapy were retrospectively analyzed. Patients were divided into two groups according to the number of high risk factors (group 1, single high risk factor; group 2, two or more high risk factors). Results A total of 93 patients were enrolled in the present study. Forty nine out of 93 (52.7%) patients had a single high risk factor, and 44 (47.3%) had two or more high risk factors. Statistically significant differences in stage and stromal invasion were observed between group 1 and group 2. However, age, histology, tumor size, and lymphovascular space invasion did not differ significantly between the groups. Distant recurrence occurred more frequently in group 2, and the probability of recurrence and death was higher in group 2. Conclusion Patients with two or more high risk factors had worse prognosis in early stage cervical cancer. For these patients, consideration of new strategies to improve survival may be worthwhile. Conduct of further clinical trials is warranted for development of adjuvant treatment strategies individualized to each risk group. PMID:27200308

    Abstract The benefit of adjuvant trastuzumab in disease-free and overall survival for human epidermal receptor 2–positive (HER2+) breast cancer patients is well established. However, the effect of trastuzumab on locoregional control remains unclear, particularly in patients treated with adjuvant radiotherapy (RT). In this study, we investigated the locoregional benefit of trastuzumab in patients with HER2+ breast cancer after adjuvant RT. Using a single institutional database, we identified 278 patients with stage II/III invasive HER2+ breast tumors receiving adjuvant RT between January 2008 and July 2011. We compared the locoregional outcomes of 134 patients who received trastuzumab to 144 patients without trastuzumab within the same period. Clinical and biological factors that might impact on the locoregional benefit of trastuzumab were also assessed. At the median follow-up of 45 months, trastuzumab significantly lowered the risk of locoregional recurrence (LRR) with a 3-year LRR rate of 2.4% versus 7.5% for the cohort with and without trastuzumab (P = 0.019). Trastuzumab was associated with a more significant locoregional benefit in the hormone receptor–positive (HR+)/HER2+ subgroup, with a 3-year LRR of 0% versus 6.7% in the cohort with and without trastuzumab (P = 0.027). For HR−/HER2+ breast tumor patients, the 3-year LRR rate was still lower for the cohort with trastuzumab (4.7% vs 8.6%). However, statistical significance was not found (P = 0.179). Both univariate and multivariate analyses confirmed that trastuzumab treatment was the only significant predictive factor for LRR (hazard ratio, 4.05; 95% confidence interval, 1.07–15.35; P = 0.039). Adjuvant trastuzumab in addition to RT is associated with significant reduced LRR risk in HER2+ breast cancer. PMID:27512838

    Nonsteroidal anti-inflammatory Drugs (NSAIDs) is one of the most commonly use medication for treatment of knee osteoarthritis which has the analgesic and anti-inflammation by inhibition of prostaglandin synthesis via COX-1 and COX-2 isoenzyme. The problem of prolong using NSAIDs has side effect on kidney, liver and GI system. Curcumin longa extract Curcumin) is the Asian herbal medicine that has the anti-inflammatory effect by down regulate activation of NF-kappaB and proinflammatory cytokines such as Tumor Necrotic Factor-alpha, Interleukin-1, Interleukin-8, and Nitric Oxide Syntase. Many research data had advocate for the combination therapy which can increase safety and efficacy with less side effect compare with monotherapy regimen especially when the medicine has the different mechanism of action. The present study is the double blind prospective randomized control trial to evaluate the efficacy of curcumin as an adjuvant therapy of diclofenac in primary knee osteoarthritis. 44 patients were randomized to take NSAIDs (diclofenac) 75 mg/d with placebo and the other 44 took NSAIDs (diclofenac) 75 mg/d with curcumin 1,000 mg/d for 3 months. The authors evaluated the Visual Analog Scale (VAS) for pain and Knee Injury and Osteoarthritis Outcome Score (KOOS) every month for 3 months. At the end of study 36 patients were completed for the first group and 37 for the study group. There was no difference in VAS [p-value = 0.923 (F = 0.009)]. The KOOS was analyzed in 5 categories symptom, pain, function in daily living, function in sport and recreation and knee related quality of life. The curcumin with diclofenac group had tendency to be better in Pain and Function in daily living, but there were no statistic different in all group [p-value = 0.412 (F = 0.683), p-value = 0.814 (F = 0.056), p-value = 0.446 (F = 0.589), p-value = 0.224 (F = 1.511) and p-value = 0.938 (F = 0.006)].

    Primary cardiac tumors do not occur frequently, and only one quarter of them, chiefly sarcomas, are malignant. Patients with angiosarcoma typically have a shorter survival time than do patients with other sarcomas, and the prognosis for survival depends strictly on the stage of the disease at the time of diagnosis and the possibility of complete surgical excision. Chemotherapy and radiotherapy have well-established postoperative roles because of the high probability of metastasis. We report the case of a 25-year-old man who presented with pericardial effusion and echocardiographic evidence of an intracavitary right atrial mass but without the bulky, infiltrative growth typical of this location of the disease. Malignancy was suggested by the clinical presentation, the location of the mass in the right side of the heart, and the absence of conditions favoring thrombus formation. After complete surgical excision, the mass was confirmed to be an angiosarcoma. Conventional adjuvant chemotherapy and maintenance therapy with inhibitors of CD117 (c-kit) and vascular endothelial growth factor relieved the patient's clinical symptoms and enabled his long-term, disease-free survival. In addition to reporting this case, we discuss aspects of the diagnosis and treatment of angiosarcoma.

    Giant-cell reparative granuloma (GCRG) or a solid variant of an aneurysmal bone cyst (ABC) is an uncommon benign reactive lesion with a predilection for the small tubular bones of the hands and feet. Treatment usually involves wide resection or amputation because of unacceptable high recurrence rates after curettage. Adjuvant therapy usually is applied to reduce the recurrence of locally aggressive bone tumors. We report 2 cases of GCRG that were treated successfully with curettage, adjuvant phenol and ethanol, and autogenous bone grafting.

    Background Cancer Care Ontario’s Program in Evidence-Based Care (pebc) recently created an evidence-based consensus guideline on the systemic treatment of early breast cancer. The evidence for the guideline was compiled using a systematic review to answer the question “What is the optimal systemic therapy for patients with early-stage, operable breast cancer, when patient and disease factors are considered?” The question was addressed in three parts: cytotoxic chemotherapy, endocrine treatment, and her2 (human epidermal growth factor receptor 2)–targeted therapy. Methods For the systematic review, the literature in the medline and embase databases was searched for the period January 2008 to May 2014. The Standards and Guidelines Evidence directory of cancer guidelines and the Web sites of major oncology guideline organizations were also searched. The basic search terms were “breast cancer” and “systemic therapy” (chemotherapy, endocrine therapy, targeted agents, ovarian suppression), and results were limited to randomized controlled trials (rcts), guidelines, systematic reviews, and meta-analyses. Results Several hundred documents that met the inclusion criteria were retrieved. Meta-analyses from the Early Breast Cancer Trialists’ Collaborative Group encompassed many of the rcts found. Several additional studies that met the inclusion criteria were retained, as were other guidelines and systematic reviews. Summary The results of the systematic review constitute a comprehensive compilation of high-level evidence, which was the basis for the 2014 pebc guideline on systemic therapy for early breast cancer. The review of the evidence for systemic endocrine therapy (adjuvant tamoxifen, aromatase inhibitors, and ovarian ablation and suppression) is presented here; the evidence for chemotherapy and her2-targeted treatment—and the final clinical practice recommendations—are presented separately in this supplement.

    Abstract Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor in gastrointestinal tracts; however, the synchronous or metachronous coexistence of GIST with additional primary malignancy is not common. Here, we present an unusual case of gastric GIST with metachronous primary lung adenocarcinoma diagnosed during his adjuvant treatment with oral receptor tyrosine kinase inhibitor imatinib mesylate (400 mg daily). After 6-month use of imatinib, the patient suffered from dry cough and dyspnea. Subsequent lung biopsy demonstrated adenocarcinoma with diffuse interstitial changes. Our research emphasizes the possibility of an additional primary tumor with GIST, and reminds the clinicians to strengthen the surveillance of the additional cancer during the follow-up of GIST patients.

    Purpose The ACOSOG (American College of Surgeons Oncology Group) Z9001 (Alliance) study, a randomized, placebo-controlled trial, demonstrated that 1 year of adjuvant imatinib prolonged recurrence-free survival (RFS) after resection of primary GI stromal tumor (GIST). We sought to determine the pathologic and molecular factors associated with patient outcome. Patients and Methods There were 328 patients assigned to the placebo arm and 317 to the imatinib arm. Median patient follow-up was 74 months. There were 645 tumor specimens available for mitotic rate or mutation analysis. Results RFS remained superior in the imatinib arm (hazard ratio, 0.6; 95% CI, 0.43 to 0.75; Cox model–adjusted P < .001). On multivariable analysis of patients in the placebo arm, large tumor size, small bowel location, and high mitotic rate were associated with lower RFS, whereas tumor genotype was not significantly associated with RFS. Multivariable analysis of patients in the imatinib arm yielded similar findings. When comparing the two arms, imatinib therapy was associated with higher RFS in patients with a KIT exon 11 deletion of any type, but not a KIT exon 11 insertion or point mutation, KIT exon 9 mutation, PDGFRA mutation, or wild-type tumor, although some of these patient groups were small. Adjuvant imatinib did not seem to alter overall survival. Conclusion Our findings show that tumor size, location, and mitotic rate, but not tumor genotype, are associated with the natural history of GIST. Patients with KIT exon 11 deletions assigned to 1 year of adjuvant imatinib had a longer RFS. PMID:24638003

    Photodynamic therapy (PDT) is a treatment option for several forms of human cancer, and like traditional chemotherapy and ionizing radiation therapy, PDT alone is not curative for some cases. Recent efforts have aimed at developing strategies for adjuvant therapy for PDT. Given the nature of PDT-mediated cell damage, immunotherapy is a promising adjuvant for long-term control of solid tumors. A candidate immune stimulant for use with PDT is monophosphoryl lipid A (MLA), a non-toxic fraction of the endotoxin molecule. The hypothesis is that adjuvant MLA immunotherapy with PDT will improve local tumor control and prevent growth of subsequently implanted tumor cells when compared to PDT alone. To date, no significant differences in circulating leukocyte populations or tumor infiltrating lymphocyte populations have been identified in 9L tumor-bearing F344 rats after systemic administrations of MLA. Likewise, no significant difference has been identified in local tumor control following PDT of 9L tumors with or without adjuvant MLA. Further results are pending.

    Aims Contemporary adjuvant treatment for early breast cancer is associated with improved survival but at the cost of increased risk of cardiotoxicity and cardiac dysfunction. We tested the hypothesis that concomitant therapy with the angiotensin receptor blocker candesartan or the β-blocker metoprolol will alleviate the decline in left ventricular ejection fraction (LVEF) associated with adjuvant, anthracycline-containing regimens with or without trastuzumab and radiation. Methods and results In a 2 × 2 factorial, randomized, placebo-controlled, double-blind trial, we assigned 130 adult women with early breast cancer and no serious co-morbidity to the angiotensin receptor blocker candesartan cilexetil, the β-blocker metoprolol succinate, or matching placebos in parallel with adjuvant anticancer therapy. The primary outcome measure was change in LVEF by cardiac magnetic resonance imaging. A priori, a change of 5 percentage points was considered clinically important. There was no interaction between candesartan and metoprolol treatments (P = 0.530). The overall decline in LVEF was 2.6 (95% CI 1.5, 3.8) percentage points in the placebo group and 0.8 (95% CI −0.4, 1.9) in the candesartan group in the intention-to-treat analysis (P-value for between-group difference: 0.026). No effect of metoprolol on the overall decline in LVEF was observed. Conclusion In patients treated for early breast cancer with adjuvant anthracycline-containing regimens with or without trastuzumab and radiation, concomitant treatment with candesartan provides protection against early decline in global left ventricular function.

    The cardiotoxic effects of adjuvant cancer treatments (i.e., chemotherapy and radiation treatment) have been well documented, but the effects on peripheral cardiovascular function are still unclear. We hypothesized that cancer survivors i) would have decreased resting endothelial function; and ii) altered muscle deoxygenation response during moderate intensity cycling exercise compared to cancer-free controls. A total of 8 cancer survivors (~70 months post-treatment) and 9 healthy controls completed a brachial artery FMD test, an index of endothelial-dependent dilation, followed by an incremental exercise test up to the ventilatory threshold (VT) on a cycle ergometer during which pulmonary V̇O2 and changes in near-infrared spectroscopy (NIRS)-derived microvascular tissue oxygenation (TOI), total hemoglobin concentration ([Hb]total), and muscle deoxygenation ([HHb] ≈ fractional O2 extraction) were measured. There were no significant differences in age, height, weight, and resting blood pressure between cancer survivors and control participants. Brachial artery FMD was similar between groups (P = 0.98). During exercise at the VT, TOI was similar between groups, but [Hb]total and [HHb] were significantly decreased in cancer survivors compared to controls (P < 0.01) The rate of change for TOI (ΔTOIΔ/V̇O2) and [HHb] (Δ[HHb]/ΔV̇O2) relative to ΔV̇O2 were decreased in cancer survivors compared to controls (P = 0.02 and P = 0.03 respectively). In cancer survivors, a decreased skeletal muscle microvascular function was observed during moderate intensity cycling exercise. These data suggest that adjuvant cancer therapies have an effect on the integrated relationship between O2 extraction, V̇O2 and O2 delivery during exercise.

    Effective treatments for recurrent/metastatic human papillomavirus-positive (HPV+) head and neck squamous cell cancer (HNSCC) are limited. To aid treatment development, we characterized a novel murine model of recurrent/metastatic HPV+ HNSCC. Further analysis of the parental tumor cell line and its four recurrent/metastatic derivatives led to preclinical testing of an effective treatment option for this otherwise fatal disease. Reverse phase protein arrays identified key signaling cascades in the parental and recurrent/metastatic cell lines. While protein expression profiles differed among the recurrent/metastatic cell lines, activated proteins associated with the mTOR signaling cascade were a commonality. Based on these data, mTOR inhibition was evaluated as an adjuvant treatment for recurrent/metastatic disease. mTOR activity and treatment response were assessed in vitro by western blot, Seahorse, proliferation, clonogenic, and migration assays. Standard-of-care cisplatin/radiation therapy (CRT) versus CRT/rapamycin were compared in vivo. Low-dose rapamycin inhibited mTOR signaling, decreasing proliferation (43%) and migration (62%) while it enhanced CRT-induced cytotoxicity (3.3 fold) in clonogenic assays. Furthermore, rapamycin re-sensitized CRT-resistant, metastatic tumors to treatment in vivo, improving long-term cures (0–30% improved to 78–100%, depending on the recurrent/metastatic cell line) and limiting lymph node metastasis (32%) and lung metastatic burden (30 fold). Studies using immune compromised mice suggested rapamycin's effect on metastasis is independent of the adaptive immune response. These data suggest a role of mTOR activation in HPV+ HNSCC recurrent/metastatic disease and that adjuvant mTOR inhibition may enhance treatment of resistant, metastatic cell populations at the primary site and limit distant metastasis.

    Rheumatoid arthritis (RA) patients under immunosuppressive therapy are particularly susceptible to infections, mainly of the respiratory tract, thus vaccination may represent a strategy to reduce their incidence in this vulnerable population. In the 2009-10 influenza season, the safety and immunogenicity of co-administered non-adjuvanted seasonal and MF59-adjuvanted pandemic influenza vaccines were evaluated in this study in 30 RA patients under therapy with anti-tumour necrosis factor (TNF)-α agents or Abatacept and in 13 healthy controls (HC). Patients and HC underwent clinical and laboratory evaluation before (T0), 1 (T1) and 6 months (T2) after vaccinations. No severe adverse reactions, but a significant increase in total mild side effects in patients versus HC were observed. Both influenza vaccines fulfilled the three criteria of the Committee for Proprietary Medicinal Products (CPMP). Seroconversion rate for any viral strain in patients and HC was, respectively, 68 versus 45 for H1-A/Brisbane/59/07, 72 versus 81 for H3-A/Brisbane/10/07, 68 versus 54 for B/Brisbane/60/08 and 81 versus 54 for A/California/7/2009. A slight increase in activated interferon (IFN)-γ-, TNF-α- or interleukin (IL)-17A-secreting T cells at T1 compared to T0, followed by a reduction at T2 in both patients and HC, was registered. In conclusion, simultaneous administration of adjuvanted pandemic and non-adjuvanted seasonal influenza vaccines is safe and highly immunogenic. The largely overlapping results between patients and HC, in terms of antibody response and cytokine-producing T cells, may represent further evidence for vaccine safety and immunogenicity in RA patients on biologicals.

    The purpose of this study was to retrospectively analyze the feasibility of outpatient management without initial assessment for febrile patients undergoing adjuvant chemotherapy for breast cancer. A total of 131 consecutive patients with breast cancer treated with adjuvant or neoadjuvant chemotherapy from 2011 to 2013 at Osaka Medical College Hospital (Osaka, Japan) were retrospectively reviewed. In the case of developing a fever (body temperature, ≥38°C), the outpatients had been instructed to take previously prescribed oral antibiotics for 3 days without any initial assessment, and if no improvement had occurred by then, they were required to visit the hospital for examination and to undergo treatment based on the results of a risk assessment for complications. The primary aim of the present study was to assess the outcome of febrile episodes, while the secondary aim was to assess the incidence of febrile episodes, hospitalizations, and the type of chemotherapy. The 131 patients received 840 chemotherapy administrations. Fifty-five patients (42.0%) had a total of 75 febrile episodes after 840 chemotherapy administrations (8.9%). Treatment failure occurred in 12 of the 75 episodes (16.0%) in 11 of the 55 patients (20.0%). Only four episodes required hospitalization. Treatment success was achieved in 63 episodes (84.0%). In conclusion, the feasibility of outpatient management without initial assessment was evaluated in the present study for febrile patients undergoing adjuvant chemotherapy for breast cancer, and the outpatient strategy regimen may be safe and convenient for these patients.

    Purpose: Breast cancer treatment disparities in racial/ethnic minority and low-income populations are well documented; however, underlying reasons remain poorly understood. This study sought to identify barriers to the delivery of quality breast cancer treatment, addressing compliance with the National Quality Forum (NQF) quality metric for adjuvant hormone therapy (HT; administration of HT within 365 days of diagnosis in eligible patients) at an urban safety net hospital. Methods: This retrospective, observational study included women diagnosed with nonmetastatic, T1c or greater, estrogen and/or progesterone receptor–positive breast cancer from 2006 to 2008. Data sources included the hospital cancer registry and electronic medical record. Compliance with the NQF quality metric was defined as HT prescription within 365 days of diagnosis. Bivariate analysis compared compliant with noncompliant patients. Qualitative analysis assessed reasons for delayed compliance (HT at > 365 days) and never compliance (no HT at 4 years). Results: Of 113 eligible patients, the majority were racial/ethnic minority (56%), stage II (54%), unmarried (60%), and had public or no insurance (72%). Sixty-four percent were compliant, and 36% were noncompliant. Of the noncompliant, 78% had delayed compliance, and 22% were never compliant. Noncompliant patients were significantly more likely to be Black, Hispanic, foreign-born, and stage III at diagnosis. Ten reasons for delayed compliance were identified, including patient- and system-level barriers. Most patients (56%) had more than one reason contributing to delay. Conclusion: Urgently needed interventions to reduce disparities in breast cancer treatment should take into account obstacles inherent among immigrant and indigent populations and complexities of multidisciplinary cancer care.

    The standard treatment in children with average-risk medulloblastoma (MB) is reduced-dose radiotherapy (RT) followed by chemotherapy. However, in adults, there is no agreement on the use of adjuvant chemotherapy. We performed a retrospective analysis of adult MB patients with average-risk disease, defined as no postsurgical residual (or ≤1.5 cm(2)) and no metastatic disease (M0). Main inclusion criteria were: age >16 years, post-surgical treatment with craniospinal irradiation with or without adjuvant chemotherapy (cisplatin and etoposide ± cyclophosphamide). From 1988 to 2012 were accrued 43 average-risk MB patients treated with surgery and adjuvant RT. Fifteen (34.9 %) patients received also chemotherapy: 7 before RT, 5 after RT, and 3 before and after RT. Reasons to administer chemotherapy were presence of residual disease (even if ≤1.5 cm) and delay in RT. After a median follow up time of 10 years (range: 8-13), median survival was 18 years (95 % CI 9-28) in patients who receive RT alone, and was not reached in patients treated with RT plus chemotherapy. The survival rates at 5, 10 and 15 years were 100 %, 78.6 % (95 % CI 60.0-97.2 %) and 60.2 % (95 % CI 36.9-83.5 %), in patients treated with RT alone, and 100, 100 and 100 %, in patients treated with RT plus chemotherapy (p = 0.079). Our findings suggest a role for adjuvant chemotherapy in the treatment of average-risk MB adult patients. Further improvements might drive to add chemotherapy in average-risk setting with less favourable biological signatures (i.e., non-WNT group).

    2014-01-01

    Breast cancer is the second most common cancer in women worldwide. Although most women are diagnosed with early breast cancer, a substantial number recur due to persistent micro-metastatic disease. Systemic adjuvant chemotherapy improves outcomes and has advanced from first-generation regimens to modern dose-dense combinations. Although chemotherapy is the cornerstone of adjuvant therapy, new biomarkers are identifying patients who can forego such treatment. Neo-adjuvant therapy is a promising platform for drug development, but investigators should recognize the limitations of surrogate endpoints and clinical trials. Previous decades have focused on discovering, developing, and intensifying adjuvant chemotherapy. Future efforts should focus on customizing therapy and reducing chemotherapy for patients unlikely to benefit. In some cases, it may be possible to replace chemotherapy with treatments directed at specific genetic or molecular breast cancer subtypes. Yet, we anticipate that chemotherapy will remain a critical component of adjuvant therapy for years to come. PMID:25336961

    Breast cancer is the most common cause of cancer and cancer death worldwide. Although most patients present with localized breast cancer and may be rendered disease-free with local therapy, distant recurrence is common and is the primary cause of death from the disease. Adjuvant systemic therapies are effective in reducing the risk of distant and local recurrence, including endocrine therapy, anti-HER2 therapy, and chemotherapy, even in patients at low risk of recurrence. The widespread use of adjuvant systemic therapy has contributed to reduced breast cancer mortality rates. Adjuvant cytotoxic chemotherapy regimens have evolved from single alkylating agents to polychemotherapy regimens incorporating anthracyclines and/or taxanes. This review summarizes key milestones in the evolution of adjuvant systemic therapy in general, and adjuvant chemotherapy in particular. Although adjuvant treatments are routinely guided by predictive factors for endocrine therapy (hormone receptor expression) and anti-HER2 therapy (HER2 overexpression), predicting benefit from chemotherapy has been more challenging. Randomized studies are now in progress utilizing multiparameter gene expression assays that may more accurately select patients most likely to benefit from adjuvant chemotherapy.

    Abstract Cytokine-induced killer (CIK) cell therapy has recently been used as an adjuvant setting following resection of hepatocellular carcinoma (HCC), while its benefit remains unclear. This study aimed to evaluate the efficacy of adjuvant CIK application in solitary HCC patients undergoing curative resection with stratification of microvascular invasion (MVI). In total, specimens and data from 307 solitary HCC patients undergoing curative resection between January 2007 and December 2010 were included. Of these, 102 patients received CIK treatment after surgery (CIK group), whereas 205 patients did not (control group). Pathological evaluation was used to retrospectively determine MVI status. The CIK group had 60 MVI-negative and 42 MVI-positive patients, while the numbers in control group were 124 and 81. Kaplan-Meier and Cox regression analyses were used to validate possible effects of CIK treatment on disease free survival (DFS) and overall survival (OS) as appropriate. For all patients, the CIK group exhibited significantly higher OS than the control group (log-rank test; PDFS = 0.055, POS = 0.020). Further analysis based on MVI stratification showed that for patients with MVI, DFS and OS did not differ between the 2 groups (PDFS = 0.439, POS = 0.374). For patients without MVI, the CIK group exhibited better DFS and OS than the control group (PDFS = 0.042, POS = 0.007), and multivariate analyses demonstrated that CIK treatment was an independent prognostic factor both for DFS and OS. For solitary HCC, CIK cell therapy after curative resection improves DFS and OS for patients without MVI, but has no statistically significant survival benefit for patients with MVI. PMID:26844496

    Hormonal therapy with either tamoxifen or aromatase inhibitors is commonly used to treat women with breast cancer in both the adjuvant and recurrent disease setting. Cutaneous adverse reactions to these drugs have been rarely reported in the literature. We report an unusual case of urticarial vasculitis following the aromatase inhibitor anastrozole that localised to the unilateral trunk and mastectomy scar, and review the literature on the cutaneous adverse effects of hormonal therapy for breast cancer.

    BACKGROUND Little is known about the factors that predict for gastrointestinal stromal tumor (GIST) recurrence in patients treated with adjuvant imatinib. METHODS Risk factors for GIST recurrence were identified, and 2 risk stratification scores were developed using the database of the Scandinavian Sarcoma Group (SSG) XVIII trial, where 358 patients with high-risk GIST with no overt metastases were randomly assigned to adjuvant imatinib 400 mg/day either for 12 or 36 months after surgery. The findings were validated in the imatinib arm of the American College of Surgeons Oncology Group Z9001 trial, where 359 patients with GIST were randomized to receive imatinib and 354 were to receive placebo for 12 months. RESULTS Five factors (high tumor mitotic count, nongastric location, large size, rupture, and adjuvant imatinib for 12 months) were independently associated with unfavorable recurrence-free survival (RFS) in a multivariable analysis in the SSGXVIII cohort. A risk score based on these 5 factors had a concordance index with GIST recurrence of 78.9%. When a simpler score consisting of the 2 strongest predictive factors (mitotic count and tumor site) was devised, the groups with the lowest, intermediate high, and the highest risk had 5-year RFS of 76.7%, 47.5%, and 8.4%, respectively. Both scores were strongly associated with RFS in the validation cohort (P < .001 for each comparison). CONCLUSIONS The scores generated were effective in stratifying the risk of GIST recurrence in patient populations treated with adjuvant imatinib. Patients with nongastric GIST with a high mitotic count are at a particularly high risk for recurrence. PMID:24737415

    We reviewed 319 primary breast tumours for cytosolic pS2 content, with a median follow-up of 6 years. pS2 status correlated positively with oestradiol and progesterone receptors and negatively with Scarff, Bloom and Richardson grade. pS2 positivity was associated with longer overall survival, particularly in patients who received hormone therapy, in whom pS2 status was also predictive of the response to therapy.

    Objective To explore women's experiences of taking adjuvant endocrine therapy as a treatment for breast cancer and how their beliefs about the purpose of the medication, side effects experienced and interactions with health professionals might influence adherence. Design Qualitative study using semistructured, one-to-one interviews. Setting 2 hospitals from a single health board in Scotland. Participants 30 women who had been prescribed tamoxifen or aromatase inhibitors (anastrozole or letrozole) and had been taking this medication for 1–5 years. Results Women clearly wished to take their adjuvant endocrine therapy medication as prescribed, believing that it offered them protection against breast cancer recurrence. However, some women missed tablets and did not recognise that this could reduce the efficacy of the treatment. Women did not perceive that healthcare professionals were routinely or systematically monitoring their adherence. Side effects were common and impacted greatly on the women’s quality of life but did not always cause women to stop taking their medication, or to seek advice about reducing the side effects they experienced. Few were offered the opportunity to discuss the impact of side effects or the potential options available. Conclusions Although most women in this study took adjuvant endocrine therapy as prescribed, many endured a range of side effects, often without seeking help. Advice, support and monitoring for adherence are not routinely offered in conventional follow-up settings. Women deserve more opportunity to discuss the pros, cons and impact of long-term adjuvant endocrine therapy. New service models are needed to support adherence, enhance quality of life and ultimately improve survival. These should ideally be community based, in order to promote self-management in the longer term. PMID:24928595

    Objective. To conduct a comprehensive PRISMA-compliant systematic review and meta-analysis to evaluate the efficacy and safety of Chinese medicines (CMs) as an adjuvant therapy for unresectable HCC during transarterial chemoembolization (TACE). Methods. Main databases were searched up to October 2012 for randomized controlled trials (RCTs) evaluating the effects of CMs plus TACE on unresectable HCC compared with TACE alone. References of relevant reviews and eligible studies were also assessed. Risk ratios with 95% confidence intervals and mean difference were calculated. Heterogeneity and publication bias were examined. Results. Sixty-seven trials (N = 5,211) were included in the meta-analysis. Sensitivity analysis and random-effects model were performed for assessing significant heterogeneity. CMs plus TACE showed beneficial effects on tumor response, survival at 6, 12, 18, 24, and 36 months, quality of life, and TACE toxicity reduction compared with TACE alone. Conclusion. The results show that the use of CMs may increase the efficacy and reduce the toxicity of TACE in treating patients with unresectable HCC. These findings suggest that CMs could be considered as an adjuvant therapy for unresectable HCC patients during TACE. Larger-scale RCTs using standard methods and long-term follow-up are warranted to confirm these findings. PMID:23956773

    Purpose: To determine whether adjuvant chemoradiotherapy (CRT) improves the outcome of cervical cancer patients with intermediate risk factors. Methods and Materials: Between January 2000 and June 2006, the medical records of 735 patients who had undergone radical surgery for Stage IB-IIA cervical cancer were reviewed retrospectively. Of the 735 patients, 172 with two or more intermediate risk factors (i.e., lymphovascular space involvement, deep stromal invasion, and tumor size {>=}2 cm) were grouped as follows according to the adjuvant treatment received: 34 patients, no further treatment; 49 patients, RT; and 89 patients, CRT. The significance of the clinical parameters and recurrence-free survival of each group were analyzed. Results: Of the 172 patients with any of the intermediate risk factors, 137 (79.6%) had two or more intermediate risk factors. Of the 172 patients, 12 developed recurrences (6.4%)->(7.0%), with 6 in the pelvis and 6 in distant sites. All 12 recurrences occurred in those who had two or more intermediate risk factors (sensitivity, 100%); however, only six recurrences were detected in patients who met the Gynecologic Oncology Group criteria for the intermediate-risk group (sensitivity, 50%; Z test, p < .05). A statistically significant difference was found in the 3-year recurrence-free survival rate among the no further treatment, RT, and CRT groups (67.5%, 90.5%, and 97.5%, respectively; p < .05). The incidence of Grade 3-4 hematologic and gastrointestinal toxicities was not significantly different statistically between the RT and CRT groups (6.1% and 13.4%, respectively; p > .05). Conclusion: Postoperative adjuvant CRT can improve the outcome of cervical cancer patients with intermediate risk factors, with low increase in toxicity.

    The objective of this study was to evaluate the efficacy of thienyl phencyclidine (tenocyclidine, TCP) and its newly synthesized adamantyl derivatives containing piperidine (TAPIP), pyrolidine (TAPIR) and morpholine (TAMORF) groups, which were tested with or without standard therapy in mice poisoned with organophosphates (OPs) and carbamates. These compounds with potential activity at the N-methyl- D-aspartate and muscarinic receptors showed low acute toxicity, having LD50 values varying from 106.00 mg/kg (TCP) to >504.00 mg/kg body weight (TAMORF). TCP and its adamantyl derivatives were administered intraperitoneally (2.5 mg/kg body weight) together with atropine (10.0 mg/kg body weight) and with or without 1/4 LD50 of the oxime HI-6. Each compound administered with atropine had a therapeutic effect against poisoning with carbamates propoxur, aldicarb and Ro 02-0683 (protective ratio of tenocyclidines was from 3.99 LD50 of aldicarb to >16.00 LD50 for propoxur). However, the efficacy of those compounds in combination with atropine was lower against poisoning with the OP insecticide dichlorvos (DDVP) and chemical warfare agents soman and tabun. In soman-poisoned mice, the best therapeutic effects were obtained with the combination of HI-6 plus atropine and test compounds, with protective ratios being from 5.40 to 7.12 LD50 of soman. The results suggest that TCP and adamantyl tenocyclidines could be used in combination with atropine as antidotes in carbamate poisoning and as adjuvant therapy to HI-6 and atropine in soman poisoning.

    Background Adjuvant chemotherapy after the complete resection of non-small-cell lung cancer (NSCLC) is now the standard of care. To improve survival, it is important to identify risk factors for the continuation of adjuvant chemotherapy. In this study, we analyzed chemotherapy compliance and magnitude of the prognostic impact of the prognostic nutritional index (PNI) before adjuvant chemotherapy. Methods We conducted a retrospective review of data from 106 patients who had received adjuvant chemotherapy. The adjuvant chemotherapy consisted of an oral tegafur agent (OT) or platinum-based chemotherapy (PB). The correlations between the PNI values and recurrence-free survival (RFS) were then evaluated. Results In the PB group, the percentage of patients who completed the four planned cycles of chemotherapy was not correlated with the PNI. In the OT group, however, a significant difference was observed in the percentage of patients who completed the planned chemotherapy according to the PNI before adjuvant chemotherapy. The RFS of patients with a PNI <50 before adjuvant chemotherapy was significantly poorer than that of the patients with a PNI ≥50. A multivariate analysis showed that nodal metastasis and PNI before chemotherapy were independent predictors of the RFS. However, PNI before surgery was not a predictor of the RFS. In the subgroup analysis, PNI before chemotherapy was independent predictor of the RFS in the OT group (P=0.019), but not in the PB group (P=0.095). Conclusion The PNI before adjuvant chemotherapy influenced the treatment compliance with the planned chemotherapy in the OT group, but not the PB group. In addition, a low PNI before adjuvant chemotherapy was associated with a poor RFS in a multivariate analysis, especially in the OT group. PMID:26504397

    14 patients with transional-cell bladder cancer in stage T1N0M0G2 after transurethral bladder resection were offered adjuvant treatment with PDT. Adjuvant PDT was performed 1-1.5 months after transurethral bladder resection for superficial bladder cancer. Prior to PDT conventional and fluorescent cystoscopy were performed. In the absence of inflammation and after full epitalisation of postoperative wound a session of therapy was performed. 24 hours prior to PDT-session photosensitizer Photosens was injected intravenously in the dose of 0.8 mg per kg of body weight. Prior to PDT local anesthesia of urethra with lidocain-gel was performed. Cystoscopy was carried out. PDT was performed with diode laser "Biospec" (675 nm). During the session the place of standing diffuser and the volume of a bladder were controlled. After 7 months of observation no tumor recidivists were observed. Registered side effects were not life-threatened. 5 patients had pain or discomfort in suprapubic area, ceasing spontaneously or requiring administration of analgetics. No systemic side-effects or allergic reactions were observed. The method can be used in out-patient practice. Absence of early recidivists shows efficiency of PDT in the treatment of superficial bladder cancer. Further study is necessary to estimate optimal regimen of PDT. The further controlling of condition on the patients in this group is required. At the laboratory animals' experiment, we conducted the explorations devoted to the influence of the photodynamic effect at the prostate's tissues.

    From 1978 to 1981, 46 patients received primary radiotherapy following excisional biopsy and axillary staging procedure for Stages I and II carcinoma of the breast. The patients were divided into 2 groups: 27 patients who received radiation and completed 12 cycles of adjuvant chemotherapy (CMF or CMFP) and 19 patients who received radiation alone. All patients received radiation to the breast and regional nodes (4600 to 5000 rad) and a boost to the site of the primary tumor (1500 to 2000 rad). Median follow-up from completion of radiation was 26 months in the non-adjuvant and 24 months in the adjuvant group with a range of 12 to 49 months. Cosmesis was judged to be good to excellent in 89% (17/19) of the patients receiving radiation alone and 81% (22/27) of the patients receiving adjuvant chemotherapy. Fair to poor cosmesis in the adjuvant group was attributed primarily to increased fibrosis and reduction of breast size. The single complication for which there was an increased incidence in the adjuvant group was arm edema (22 vs. 0%). The incidence of arm edema was unrelated to T stage, type of axillary surgical procedure, number of positive nodes, addition of prednisone or sequencing of chemotherapy.

    Limited data are available regarding patterns of chemotherapy receipt and treatment-related toxicities for older women receiving adjuvant trastuzumab-based therapy. We used surveillance, epidemiology and end results (SEER)-Medicare data to identify patients ≥66 years with stage I-III breast cancer treated during 2005-2009, who received trastuzumab-based therapy. We examined patterns of chemotherapy receipt, and using multivariable logistic regression, we examined associations of age and comorbidity with non-standard chemotherapy. In propensity-weighted cohorts of women receiving standard and non-standard trastuzumab-based therapy, we also examined rates of (1) hospital events during the first 6 months of chemotherapy and (2) short-term survival. Among 2,106 women, 29.7 % were aged ≥76 and 66 % had a comorbidity score = 0. Overall, 31.3 % of women received non-standard chemotherapy. Compared to patients aged 66-70, older patients more often received non-standard chemotherapy [adjusted odds ratio (OR) = 4.1, 95 % confidence interval (CI) = 3.40-4.92 (ages 76-80); OR = 15.3, 95 %CI = 9.92-23.67 (age ≥ 80)]. However, comorbidity was not associated with receipt of non-standard chemotherapy. After propensity score adjustment, hospitalizations were more frequent in the standard (vs. non-standard) group (adjusted OR = 1.7, 95 % CI = 1.29-2.24). With a median follow-up of 2.8 years, 276 deaths occurred; the adjusted hazard ratio (HR) for death was lower in standard versus non-standard treated women (HR = 0.69, 95 % CI = 0.52-0.91). Among a population-based cohort of older women receiving trastuzumab, nearly one-third received non-standard chemotherapy, with the highest rates among the oldest women. Non-standard chemotherapy was associated with fewer toxicity-related hospitalizations but worse survival. Further exploration of treatment toxicities and outcomes for older women with HER2-positive breast cancer is warranted.

    A 64-year-old man with advanced gastric cancer presented with chief complaints of chest pain. His preoperative blood examination revealed positive results for serum HIV-antibody. His HIV-RNA level was 1.0×10 / 5 copies/mL, and his CD4lymphocyte count was 491 cell/mL; the patient was diagnosed with advanced gastric cancer and HIV infection. Distal gastrectomy with D2 lymphadenectomy and Roux-en-Y reconstruction were performed for treatment of the gastric cancer. Pathological examination revealed T3(SS)N3aM0, Stage III C cancer. After surgery, the patient was administered S-1 monotherapy as adjuvant treatment with antiretroviral therapy including tenofovir/emtricitabine and raltegravir. He completed 8 courses of S- 1 chemotherapy with no adverse events, such as a decrease in the CD4lymphocyte count or an increase in the HIV-RNA level. This patient with gastric cancer and HIV infection was safely treated using both antiretroviral therapy and chemotherapy owing to treatment intervention by chemotherapy and infectious diseases specialists.

    Background. Phase III trials of rehabilitation of paresis after stroke have proven the effectiveness of intensive and extended task practice, but they have also shown that many patients do not qualify, because of severity of impairment, and that many of those who are treated are left with clinically significant deficits. Objective. To test the value of 2 potential adjuvants to normal learning processes engaged in constraint-induced movement therapy (CIMT): greater distribution of treatment over time and the coadministration of d-cycloserine, a competitive agonist at the glycine site of the N-methyl-D-aspartate glutamate receptor. Methods. A prospective randomized single-blind parallel-group trial of more versus less condensed therapy (2 vs 10 weeks) and d-cycloserine (50 mg) each treatment day versus placebo (in a 2 × 2 design), as potential adjuvants to 60 hours of CIMT. Results. Twenty-four participants entered the study, and 22 completed it and were assessed at the completion of treatment and 3 months later. Neither greater distribution of treatment nor treatment with d-cycloserine significantly augmented retention of gains achieved with CIMT. Conclusions. Greater distribution of practice and treatment with d-cycloserine do not appear to augment retention of gains achieved with CIMT. However, concentration of CIMT over 2 weeks ("massed practice") appears to confer no advantage either.

    From 1970 to 1981, 50 patients had curative surgery for carcinoma of the cecum, ascending, or descending colon and were Stage greater than or equal to B2. In 15 cases, the lesion originated on the antimesenteric (posterolateral) bowel wall. Of seven cases (with minimum three-year follow-up) not receiving adjuvant postoperative regional irradiation, four recurred in the tumor bed/abdominal wall versus 0/3 irradiated patients. Similarly, the five-year survival was improved in the irradiated group (2/3) versus only 2/9 in the unirradiated group. Patients with transmural extension of right or left colon cancers originating on the anti mesenteric (posterolateral) bowel wall may have a high incidence of postoperative regional failure which may be decreased by adjuvant postoperative regional irradiation.

    Background The identification of early-stage colorectal cancer (CRC) with high risk of progression is one major clinical challenge, mainly due to lack of validated biomarkers. The aims of the present study were to analyze the prognostic impact of three molecular markers belonging to the ion channels and transporters family: the ether-à-go-go-related gene 1 (hERG1) and the calcium-activated KCa3.1 potassium channels, as well as the glucose transporter 1 (Glut-1); and to define the impact of adjuvant chemotherapy in conjunction with the abovementioned biomarkers, in a cohort of radically resected stage I–III CRC patients. Patients and methods The expressions of hERG1, KCa3.1, and Glut-1 were tested by immunohistochemistry on 162 surgical samples of nonmetastatic, stage I–III CRC patients. The median follow-up was 32 months. The association between biological markers, clinicopathological features, and survival outcomes was investigated by evaluating both disease-free survival and overall survival. Results Although no prognostic valence emerged for KCa3.1, evidence of a negative impact of hERG1 expression on survival outcomes was provided. On the contrary, Glut-1 expression had a positive impact. According to the results of the multivariate analysis, patients were stratified in four risk groups, based on TNM stage and hERG1/Glut-1 expression. After adjusting for adjuvant therapy, stage I and II, Glut-1-negative, and hERG1-positive patients showed the worst survival experience. Conclusion This study strongly indicates that the combination of hERG1 positivity and Glut-1 negativity behaves as a prognostic biomarker in radically resected CRC patients. This combination identifies a group of stage I and II CRC patients with a bad prognosis, even worse than that of stage III patients, regardless of adjuvant therapy accomplishment.

    Ca(2+)-loaded calmodulin normally inhibits multiple Ca(2+)-channels upon dangerous elevation of intracellular Ca(2+) and protects cells from Ca(2+)-cytotoxicity, so blocking of calmodulin should theoretically lead to uncontrolled elevation of intracellular Ca(2+). Paradoxically, classical anti-psychotic, anti-calmodulin drugs were noted here to inhibit Ca(2+)-uptake via the vanilloid inducible Ca(2+)-channel/inflamatory pain receptor 1 (TRPV1), which suggests that calmodulin inhibitors may block pore formation and Ca(2+) entry. Functional assays on TRPV1 expressing cells support direct, dose-dependent inhibition of vanilloid-induced (45)Ca(2+)-uptake at microM concentrations: calmidazolium (broad range) > or = trifluoperazine (narrow range) chlorpromazine/amitriptyline>fluphenazine>W-7 and W-13 (only partially). Most likely a short acidic domain at the pore loop of the channel orifice functions as binding site either for Ca(2+) or anti-calmodulin drugs. Camstatin, a selective peptide blocker of calmodulin, inhibits vanilloid-induced Ca(2+)-uptake in intact TRPV1(+) cells, and suggests an extracellular site of inhibition. TRPV1(+), inflammatory pain-conferring nociceptive neurons from sensory ganglia, were blocked by various anti-psychotic and anti-calmodulin drugs. Among them, calmidazolium, the most effective calmodulin agonist, blocked Ca(2+)-entry by a non-competitive kinetics, affecting the TRPV1 at a different site than the vanilloid binding pocket. Data suggest that various calmodulin antagonists dock to an extracellular site, not found in other Ca(2+)-channels. Calmodulin antagonist-evoked inhibition of TRPV1 and NMDA receptors/Ca(2+)-channels was validated by microiontophoresis of calmidazolium to laminectomised rat monitored with extracellular single unit recordings in vivo. These unexpected findings may explain empirically noted efficacy of clinical pain adjuvant therapy that justify efforts to develop hits into painkillers, selective to sensory Ca(2

    We present here the updated results after 9 years of the beginning of a trial on canine patients with malignant melanoma. This surgery adjuvant approach combined local suicide gene therapy with a subcutaneous vaccine composed by tumor cells extracts and xenogeneic cells producing human interleukin-2 and granulocyte-macrophage colony-stimulating factor. Toxicity was absent or minimal in all patients (0≤VCOG-CTCAE grade≤1). With respect to surgery-treated controls (ST), the complete surgery (CS) arm of this combined treatment (CT) significantly increased the fraction of local disease-free patients from 13 to 81% and distant metastases free from 32 to 84%. Even though less effective than the CS arm, the partial surgery (PS) arm of this CT was significantly better controlling the disease than only surgery (14% while PS-ST: 0%, P<0.01 and CS-ST: 5%, P<0.05). In addition, CT produced a significant sevenfold (CS) and threefold (PS) increase in overall survival. The CS-CT arm significantly improved both CS-ST metastasis-free- and melanoma overall survival from 99 days (respective ranges: 11-563 and 10-568) to >2848 days (81-2848 and 35-2848). Thus, more of 50% of our CT patients died of melanoma unrelated causes, transforming a lethal disease into a chronic one. Finally, surgery adjuvant CT delayed or prevented post-surgical recurrence and distant metastasis, significantly improved disease-free and overall survival maintaining the quality of life. Long-term safety and efficacy of this treatment are supported by the high number of CT patients (283) and extensive follow-up (>9 years). The successful clinical outcome encourages the further translation of similar approaches to human gene therapy trials. PMID:23059870

    Purpose To evaluate the risk of locoregional recurrence (LRR) associated with locoregional treatment of women with primary breast cancer tumors negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (triple-negative breast cancer [TNBC]). Patients and Methods Patients diagnosed with TNBC were identified from a cancer registry in a single institution (n=768). LRR-free survival was estimated using Kaplan-Meier analysis. The Cox proportional hazards regression model was used to determine risk of LRR on the basis of locoregional management: breast-conserving therapy (BCT; ie, lumpectomy and adjuvant radiation therapy [RT]) and modified radical mastectomy (MRM) in the TNBC population and T1-2N0 subgroup. Results At a median follow-up of 7.2 years, 77 patients (10%) with TNBC developed LRR. Five-year LRR-free survival was 94%, 85%, and 87% in the BCT, MRM, and MRM + RT groups, respectively (P < .001). In multivariate analysis, MRM (compared with BCT), lymphovascular invasion and lymph node positivity were associated with increased LRR. Conversely, adjuvant chemotherapy was associated with decreased risk of LRR. For patients with T1-2N0 tumors, 5-year LRR-free survival was 96% and 90% in the BCT and MRM groups, respectively (P =.027), and MRM was the only independent prognostic factor associated with increased LRR compared with BCT (hazard ratio, 2.53; 95% CI, 1.12 to 5.75; P= .0264). Conclusion Women with T1-2N0 TNBC treated with MRM without RT have a significant increased risk of LRR compared with those treated with BCT. Prospective studies are warranted to investigate the benefit of adjuvant RT after MRM in TNBC. PMID:21670451

    Being the second cancer for men and the third cancer for women in France, colorectal cancer represents a serious public health issue. Its incidence has increased these last years and despite new therapeutics being developed, it still has a bad prognostic. Thanks in part to Hemoccult national mass screening program, its diagnosis is made possible at an earlier stage, which makes a surgical curative resection and the carrying out of adjuvant chemotherapy possible. For stage III colic cancer that has been surgically removed, adjuvant chemotherapy by FOLFOX 4 has to be offered. Nevertheless, because of its toxicities, the patient's high age, important comorbidities or post-surgical complications, this chemotherapy occasionally cannot be done. What are the colorectal cancer prognostic factors which would guide the chemotherapy? TNM classification, number of examined lymph nodes, MSI status, and presence or not of a perforation or a perinervous, lymphatic or venous invasion is recognized prognostic factors. Also, what are the alternatives of FOLFOX 4 regimen as colorectal cancer adjuvant treatment?

    Purpose: Adjuvant radiotherapy (RT) is often considered for endometrial cancer. We studied the effect of RT and surgical treatment on patients' quality of life (QOL). Methods and Materials: All patients referred to the gynecologic oncology clinics with biopsy findings showing endometrial cancer were recruited. QOL assessments were performed using the European Organization for Research and Treatment of Cancer QOL questionnaire-C30, version 3. Assessments were obtained at study entry and at regular 3-month intervals for a maximum of 2 years. Open-ended telephone interviews were done every 6 months. Linear mixed regression models were built using QOL domain scores as dependent variables, with the predictors of surgical treatment and adjuvant RT type. Results: A total of 40 patients were recruited; 80% of the surgeries were performed by laparotomy. Significant improvements were seen in most QOL domains with increased time from treatment. Adjuvant RT resulted in significantly more severe bowel symptoms and improvement in insomnia compared with conservative follow-up. No significant adverse effect from adjuvant RT was seen on the overall QOL. Bowel symptoms were significantly increased in patients treated with laparotomy compared with laparoscopy in the patients treated with whole pelvic RT. Qualitatively, about one-half of the patients noted improvements in their overall QOL during follow-up, with easy fatigability the most prevalent. Conclusion: No significant adverse effect was seen on patients' overall QOL with adjuvant pelvic RT after the recovery period. The acute adverse effects on patients' QOL significantly improved with an increasing interval from diagnosis.

    2014-01-01

    Background. Osteosarcoma is a highly malignant bone tumour. After the second relapse, the 12-month postrelapse disease-free survival (PRDFS) rate decreases below 20%. Oral Etoposide is often used in clinical practice after surgery as an “adjuvant” outside any protocol and with only limited evidence of improved survival. Viscum album fermentatum Pini (Viscum) is an extract of mistletoe plants grown on pine trees for subcutaneous (sc) injection with immunomodulatory activity. Methods. Encouraged by preliminary findings, we conducted a study where osteosarcoma patients free from disease after second metastatic relapse were randomly assigned to Viscum sc or Oral Etoposide. Our goal was to compare 12-month PRDFS rates with an equivalent historical control group. Results. Twenty patients have been enrolled, with a median age of 34 years (range 11–65) and a median follow-up time of 38.5 months (3–73). The median PRDSF is currently 4 months (1–47) in the Etoposide and 39 months (2–73) in the Viscum group. Patients getting Viscum reported a higher quality of life due to lower toxicity. Conclusion. Viscum shows promise as adjuvant treatment in prolonging PRDFS after second relapse in osteosarcoma patients. A larger study is required to conclusively determine efficacy and immunomodulatory mechanisms of Viscum therapy in osteosarcoma patients. PMID:24803944

    AIM: To investigate the efficacy and safety of adjuvant sorafenib after curative resection for patients with Barcelona Clinic Liver Cancer (BCLC)-stage C hepatocellular carcinoma (HCC). METHODS: Thirty-four HCC patients, classified as BCLC-stage C, received adjuvant sorafenib for high-risk of tumor recurrence after curative hepatectomy at a tertiary care university hospital. The study group was compared with a case-matched control group of 68 patients who received curative hepatectomy for HCC during the study period in a 1:2 ratio. RESULTS: The tumor recurrence rate was markedly lower in the sorafenib group (15/34, 44.1%) than in the control group (51/68, 75%, P = 0.002). The median disease-free survival was 12 mo in the study group and 10 mo in the control group. Tumor number more than 3, macrovascular invasion, hilar lymph nodes metastasis, and treatment with sorafenib were significant factors of disease-free survival by univariate analysis. Tumor number more than 3 and treatment with sorafenib were significant risk factors of disease-free survival by multivariate analysis in the Cox proportional hazards model. The disease-free survival and cumulative overall survival in the study group were significantly better than in the control group (P = 0.034 and 0.016, respectively). CONCLUSION: Our study verifies the potential benefit and safety of adjuvant sorafenib for both decreasing HCC recurrence and extending disease-free and overall survival rates for patients with BCLC-stage C HCC after curative resection.

    Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of cancer therapy. This study evaluates symptoms of CIPN and CIPN-related pain and its influence on psychological functioning and potential predictors of chronic CIPN and pain. In this large prospective questionnaire study, 174 patients receiving adjuvant oxaliplatin or docetaxel were consecutively included. Patients were asked to complete a questionnaire with validated questions on peripheral neuropathy, pain, anxiety and depression, and quality of life at baseline, after the first cycle, halfway through therapy, and 1 year after baseline. Chronic CIPN symptoms (tingling and/or numbness) in the feet at 1-year follow-up were present in 63.6% of patients without preexisting neuropathy in the oxaliplatin group and in 44.8% in the docetaxel group, whereas pain in hands and feet was found in 31.3% and 35.1%, respectively. Both groups had significantly different pain profiles, and persistent pain in the docetaxel group was found to have effect on psychological function. Cumulative dose predicted oxaliplatin-induced neuropathy (P = 0.004), whereas endocrine therapy predicted peripheral pain in the docetaxel group (P = 0.04). There are important differences in acute neuropathic symptoms and chronic pain profiles in patients after oxaliplatin and docetaxel treatment. It is, however, important to recognize that chronic peripheral pain may be unrelated to neuropathy and can be caused by concomitant treatments. Future studies should focus on characterizing and distinguishing CIPN-related pain from other types of pain to determine the best outcome measures for trials on prevention or relief. PMID:26529271

    Purpose We conducted a randomized trial comparing adjuvant treatment with edrecolomab versus observation in patients with resected, low-risk, stage II colon cancer. This study also prospectively studied patient- and tumor-specific markers of treatment outcome. Patients and Methods After surgical resection, patients with stage II colon cancer were randomly assigned to either five infusions of edrecolomab at 28-day intervals or observation without adjuvant therapy. Results Final accrual included 1,738 patients; 865 patients received edrecolomab, and 873 patients were observed without adjuvant treatment. Median follow-up time was 7.9 years. There were no significant outcome differences between study arms (overall survival [OS], P = .71; disease-free survival, P = .64). The combined 5-year all-cause OS was 0.86 (95% CI, 0.84 to 0.88), and the combined 5-year disease-specific OS was 0.93 (95% CI, 0.91 to 0.94). The relationships between demographic and histopathologic factors and survival differed for all-cause and disease-specific survival outcomes, but no combined prognostic factor model was found to adequately classify patients at higher risk of recurrence or death as a result of colon cancer. Conclusion Edrecolomab did not prolong survival. Consequently, this large study with a long duration of follow-up provided unique data concerning the natural history of resected stage II colon cancer. Prognostic factors identified in previous retrospective and pooled analyses were associated with survival outcomes in this stage II patient cohort. Results from ongoing molecular marker studies may enhance our ability to determine the risk profile of these patients. PMID:21747085

    Indomethacin (IMC), a nonsteroidal anti-inflammatory drug, has been used in the treatment of rheumatoid arthritis (RA), although its clinical use has been limited by its systemic side effects that include gastrointestinal lesions. Therefore, the development of IMC formulations that do not cause gastrointestinal lesions is highly anticipated. In this study, we designed new topical formulations containing IMC solid nanoparticles (IMCnano gel ointment), and investigated their pharmacokinetics. In addition, we demonstrate the preventive effects of this topical application of IMC nanoparticles on inflammation in adjuvant-induced arthritis rat (AA rat). The IMCnano gel ointment was prepared using Bead Smash 12 (a bead mill) and additives including 2-hydroxypropyl-β-cyclodextrin, methylcellulose and Carbopol 934; the mean particle size of the IMC nanoparticles was 173 ± 91 nm (means ± S.D.). The application of the IMCnano gel ointment attenuated the increase in paw edema of the hind feet of AA rats in comparison with AA rats treated with gel ointment containing IMC microparticles (IMCmicro gel ointment, particle diameter 17.1 ± 11.6 mm, means ± S.D). In addition, the accumulation of IMC from the IMCnano gel ointment in skin tissue was significantly large than for the IMCmicro gel ointment; however, the plasma IMC concentrations were similar for the IMCmicro and IMCnano gel ointments. Our findings suggest that the dermal application of nanoparticles may enable a medication to be applied without high-systemic drug levels, which could provide efficient and effective therapy that spares patients from unwanted side effects. A formulation of a topical drug delivery system using IMC nanoparticles may provide a delivery option for the clinical treatment of RA.

    Purpose/Objectives: To assess the effect and toxicity of hypofractionated high-dose intensity modulated radiation therapy (IMRT) with concurrent and adjuvant temozolomide (TMZ) in 46 patients with newly diagnosed glioblastoma multiforme (GBM). Methods and Materials: All patients underwent postsurgical hypofractionated high-dose IMRT. Three layered planning target volumes (PTVs) were contoured. PTV1 was the surgical cavity and residual tumor on T1-weighted magnetic resonance images with 5-mm margins, PTV2 was the area with 15-mm margins surrounding the PTV1, and PTV3 was the high-intensity area on fluid-attenuated inversion recovery images. Irradiation was performed in 8 fractions at total doses of 68, 40, and 32 Gy for PTV1, PTV2, and PTV3, respectively. Concurrent TMZ was given at 75 mg/m{sup 2}/day for 42 consecutive days. Adjuvant TMZ was given at 150 to 200 mg/m{sup 2}/day for 5 days every 28 days. Overall and progression-free survivals were evaluated. Results: No acute IMRT-related toxicity was observed. The dominant posttreatment failure pattern was dissemination. During a median follow-up time of 16.3 months (range, 4.3-80.8 months) for all patients and 23.7 months (range, 12.4-80.8 months) for living patients, the median overall survival was 20.0 months after treatment. Radiation necrosis was diagnosed in 20 patients and was observed not only in the high-dose field but also in the subventricular zone (SVZ). Necrosis in the SVZ was significantly correlated with prolonged survival (hazard ratio, 4.08; P=.007) but caused deterioration in the performance status of long-term survivors. Conclusions: Hypofractionated high-dose IMRT with concurrent and adjuvant TMZ altered the dominant failure pattern from localized to disseminated and prolonged the survival of patients with GBM. Necrosis in the SVZ was associated with better patient survival, but the benefit of radiation to this area remains controversial.

    Background and Objective: Radiation therapy (RT) is part of standard adjuvant treatment for breast cancer. Earlier studies demonstrated increased cardiac morbidity and mortality from this. Coronary Calcium scanning utilizing Multidetector Computed Tomography (MDCT) can detect early atherosclerosis in coronary arteries by identifying the amount of calcifications. In our study we employed these tools to detect occult atherosclerosis at least 5 years following breast RT. Methods: We evaluated 20 asymptomatic patients, <60 years old, treated with RT at least 5 years prior to enrollment. Nine received RT to the left and 11 to the right chest wall. The median interval between RT and calcium scan was 8 years. All patients were treated with external beam RT using tangential technique. All patients underwent MDCT to compute volumetric and Agatston calcium scores of the coronary arteries and the aorta. Results: Eleven patients had RT to the right chest wall, and eight had a calcium score of 0, while two had minimally elevated scores and one patient had a significantly elevated score. Meanwhile nine patients had RT to the left chest wall, and seven had a calcium score of 0. None had significantly elevated scores. In the aorta, 11 of 20 patients had a score of 0, while 8 of 20 had minimally elevated scores. Conclusion: In contrast to studies demonstrating increased cardiovascular morbidity, our pilot study did not detect significant occult atherosclerosis using MDCT of the coronaries and aorta of patients assessed five or more years following radiation for treatment of breast cancer.

    The objective of this cross-sectional study was to determine lumbar spine bone mineral density (BMD) in breast cancer patients previously treated with adjuvant chemotherapy. Sixteen of 27 patients who received adjuvant chemotherapy became permanently amenorrheic as a result of chemotherapy. BMD was measured at the lumbar spine using dual energy X-ray absorptiometry (DEXA). Chemotherapy drugs and dosages along with a history of risk factors for reduced bone density including activity level, tobacco and/or alcohol use, metabolic bone disease, family history, and hormone exposure were identified. Results showed that women who became permanently amenorrheic as a result of chemotherapy had BMD 14% lower than women who maintained menses after chemotherapy. Chemotherapy-treated women who maintained ovarian function had normal BMD. This study suggests that women who have premature menopause as a result of chemotherapy for breast cancer are at increased risk of bone loss and may be at risk for early development of osteoporosis. Women who maintain menses do not appear to be at risk for accelerated trabecular bone loss.

    2016-06-01

    Considerable debate exists regarding the potential antineoplastic effect of dietary long-chain n-3 PUFA contained in fatty fishes. Since the majority of published data has proven that their intake does not induce toxic or carcinogenic effects in humans, their possible preventive use against cancer has been suggested. On the other hand, it is unlikely that they could be effective in cancer patients as a single therapy. Nevertheless, a considerable effort has been put forth in recent years to evaluate the hypothesis that n-3 PUFA might improve the antineoplastic efficiency of currently used anticancer agents. The rationale for this therapeutic combinatory strategy is trying to increase cancer sensitivity to conventional therapies. This could allow the use of lower drug/radiation doses and, thereby, a reduction in the detrimental health effects associated with these treatments. We will here critically examine the studies that have investigated this possibility, by focusing particularly on the biological and molecular mechanisms underlying the antineoplastic effect of these combined treatments. A possible use of n-3 PUFA in combination with the innovative single-targeted anti-cancer therapies, that often are not completely devoid of dangerous side-effects, is also suggested. PMID:27172872

    The outcome after curative resection for hepatocellular carcinoma (HCC) is still unsatisfactory because of the high rate of recurrence of HCC, including intrahepatic metastasis originating from the primary carcinoma and multicentric carcinogenesis after surgery. The rate of recurrence, particularly of multicentric carcinogenesis after surgery, is affected by persistent active hepatitis and hepatic fibrosis caused by chronic hepatitis B or C. In patients with hepatitis B virus (HBV)-related HCC, a high viral load is a strong risk factor for HCC recurrence. Nucleos(t)ide analogues improve the outcome after curative resection for HBV-related HCC. Interferon therapy improves the outcome after curative resection for hepatitis C virus (HCV)-related HCC by decreasing recurrence and preserving or improving liver function when treatment is successful. Low-dose intermittent interferon therapy has also been reported to be effective in suppressing HCC recurrence. New antiviral agents including protease or polymerase inhibitors are expected to be effective because these agents can eradicate HCV in most patients who receive such treatment. PMID:24159595

    Our aim in this study was to develop a prognostic scoring system with which to identify patients most likely to benefit from adjuvant chemolipiodolization (ACL) after liver resection for hepatocellular carcinoma (HCC). Data from 1150 HCC patients who underwent liver resection between 2002 and 2008 at the Eastern Hepatobiliary Surgery Hospital were used to develop the scoring system. Patients were stratified into prognostic subgroups using the new scoring system, and the outcomes of patients who received ACL and those who did not were compared in each subgroup. Using data from 379 patients operated on between 2008 and 2010 for validation, the scoring system had a concordance index (C-index) of 0.75 for predicting post-resectional overall survival (OS). It optimally stratified patients into three prognostic subgroups with scores of 0–5, 6–9 and ≥ 10, having better, medium and worse survival outcomes, respectively. A difference in OS between ACL and non-ACL patients was only detected in the subgroup with scores ≥ 10 (1-, 3-, and 5-year OS rates: 63.9%, 22.6%, and 9.0% vs. 33.8%, 5.6%, and 2.8%, p = 0.001). Our proposed scoring system provides an effective tool for selecting the patients most likely to benefit from ACL. PMID:27027439

    Purpose To examine the effects of Reiki as an adjuvant therapy to opioid therapy for postoperative pain control in pediatric patients. Methods This was a double-blind, randomized controlled study of children undergoing dental procedures. Participants were randomly assigned to receive either Reiki therapy or the control therapy (sham Reiki) preoperatively. Postoperative pain scores, opioid requirements, and side effects were assessed. Family members were also asked about perioperative care satisfaction. Multiple linear regressions were used for analysis. Results Thirty-eight children participated. The blinding procedure was successful. No statistically significant difference was observed between groups on all outcome measures. Implications Our study provides a successful example of a blinding procedure for Reiki therapy among children in the perioperative period. This study does not support the effectiveness of Reiki as an adjuvant therapy to opioid therapy for postoperative pain control in pediatric patients. PMID:24439640

    With the aging of the Chinese population, it seems obvious that the number of elderly patients with the disease of colorectal carcinoma grows significantly. Meanwhile, no evidence-based practical guideline for the treatment of colorectal carcinoma are available in this particular age group. Therefore, the concept of integrative management has been brought up by the Colorectal Cancer Center of the Second Affiliated Hospital of Zhejiang University, which combines the processes of surgery, perioperative rehabilitation and adjuvant chemotherapy together. In this way, the cooperation and complementarity between different clinical departments could cooperate and complete tasks together to integrate the treatment processes into a cohesive one. To achieve the goal of integrative management, the project is divided into horizontal and vertical aspects. The horizontal integration means the cooperation between different clinical departments, which is also known as multi-discipline treatment (MDT). The vertical integration reflects the completeness of the entire treatment under the goal of consistency, strictness and job separation, which could also be explained as the clinical pathway. Furthermore, this review stresses on the integrative strategy of both clinical and biochemical indexes rehabilitation, as well as the operation and postoperative adjuvant chemotherapy which has been put in execution several years by the Colorectal Cancer Center of the Second Affiliated Hospital of Zhejiang University.

  2. Linking Estrogen-Induced Apoptosis With Decreases in Mortality Following Long-term Adjuvant Tamoxifen Therapy

    PubMed Central

    2014-01-01

    The impressive first results of the Adjuvant Tamoxifen: Longer Against Shorter (ATLAS) and the adjuvant Tamoxifen To offer more (aTTom) trials both demonstrate that 10 years of tamoxifen is superior to five years of treatment. Tamoxifen is a nonsteroidal antiestrogen that blocks estrogen-stimulated tumor growth. Paradoxically, mortality decreases dramatically only in the decade after long-term tamoxifen is stopped. It is proposed that the evolution and clonal selection of micrometastases that acquire tamoxifen resistance now become increasingly vulnerable to endogenous estrogen-induced apoptosis. Laboratory and clinical studies confirm the concept, and supporting clinical evidence from the estrogen-alone trial in the Women’s Health Initiative (WHI), demonstrate that long-term estrogen-deprived women given exogenous physiologic estrogen have a decreased incidence of breast cancer and decreased mortality. It is proposed that a natural process of apoptosis is recruited to execute the long-term survival benefit of stopping ten years of adjuvant tamoxifen, but only after clonal selection of vulnerable breast cancer cells in an estrogen-deprived environment.

The endometrial carcinomas included two stage Ia, four stage Ib, two stage Ic and two stage IIIc. Three tumors were Grade 1, six were Grade 2, and one was Grade 3. The tumor was limited to the endometrium in two cases. Myometrial invasion was limited to the inner half of the myometrium in five cases and involved the outer half in three. A mild degree of lymphovascular space invasion was identified in five cases. Deep cervical invasion was recognized in one case. The cell types comprised nine endometrioid adenocarcinomas and one serous carcinoma. Five of eight postmenopausal endometrial carcinomas were associated with polypoid endometrial lesions composed of cystically dilated atrophic and proliferative glands widely separated by fibrotic stroma. Two patients with retroperitoneal lymph node metastases died of endometrial cancer. One patient developed a contralateral breast cancer during tamoxifen treatment. No patient died of breast cancer. We did not demonstrate a higher frequency of either high-grade tumors or unfavorable histologic subtypes in tamoxifen-treated Japanese breast cancer patients.

    Purpose: To determine the rate and magnitude of late genitourinary (GU) and gastrointestinal (GI) toxicities after salvage or adjuvant radiotherapy (RT) for prostate cancer, and to determine predictive factors for these toxicities. Methods and Materials: A large multi-institutional database that included 959 men who received postoperative RT after radical prostatectomy (RP) was analyzed: 19% received adjuvant RT, 81% received salvage RT, 78% were treated to the prostate bed only, and 22% received radiation to the pelvis. Results: The median follow-up time was 55 months. At 5 years, 10% of patients had Grade 2 late GU toxicity and 1% had Grade 3 late GU toxicity, while 4% of patients had Grade 2 late GI toxicity and 0.4% had Grade 3 late GI toxicity. Multivariate analysis demonstrated that adjuvant RT (p = 0.03), androgen deprivation (p < 0.0001), and prostate bed-only RT (p = 0.007) predicted for Grade 2 or higher late GU toxicity. For GI toxicity, although adjuvant RT was significant in the univariate analysis, no significant factors were found in the multivariate analysis. Conclusions: Overall, the number of high-grade toxicities for postoperative RT was low. Therefore, adjuvant and salvage RT can safely be used in the appropriate settings.

    In the last 20 years, several clinical trials on neoadjuvant chemotherapy and chemo-radiotherapy as a therapeutic approach for locally advanced gastric cancer have been performed. Even if more data are necessary to define the roles of these approaches, the results of preoperative treatments in the combined treatment of gastric adenocarcinoma are encouraging because this approach has led to a higher rate of curative surgical resection. Owing to the results of most recent randomized phase III studies, neoadjuvant chemotherapy for locally advanced resectable gastric cancer has satisfied the determination of level I evidence. Remaining concerns pertain to the choice of the optimal therapy regimen, strict patient selection by accurate pre-operative staging, standardization of surgical procedures, and valid criteria for response evaluation. New well-designed trials will be necessary to find the best therapeutic approach in pre-operative settings and the best way to combine old-generation chemotherapeutic drugs with new-generation molecules.

    Breast cancer is the most frequently diagnosed cancer in women worldwide and the second cause of cancer-related mortality. A total of 20–30% of patients with early-stage breast cancer develop recurrence within the first 5 years following diagnosis. Trastuzumab significantly improves overall survival and disease-free survival (DFS) in women with human epidermal growth factor receptor 2 (HER2)-positive early and locally advanced breast cancer. This study aimed to determine the factors that affect DFS following adjuvant transtuzumab therapy. A total of 62 patients treated with trastuzumab for early and locally advanced breast cancer were included in our study. Data, including pathology, treatment and treatment outcome, rate of recurrence and laboratory tests, were retrospectively collected. There was no significant association between DFS and age, menopausal status, disease stage and hormone receptor status. The median follow-up was 48.4 months. The median DFS of patients treated with adjuvant trastuzumab was 64.1 months. In addition, the median DFS was 44.3 vs. 66.8 months in patients with platelet-lymphocyte ratio (PLR) ≤200 vs. >200, respectively (log-rank test; P=0.001), and 70 vs. 45 months in patients with eosinophil count ≤70 vs. >70×103/mm3 (log-rank test; P=0.001). Our data revealed the prognostic relevance of a decrease in the peripheral blood eosinophil count and PLR value following trastuzumab therapy in breast cancer. PLR and eosinophil count measurements are cost-effective, readily available worldwide, non-invasive and safe. Combined with other markers, such as patient age, tumor stage and tumor histology, may be effectively used for patients with breast cancer. PMID:26623060

    Practice guidelines incorporate genomic tumor profiling, using results such as the Oncotype DX Recurrence Score (RS), to refine recurrence risk estimates for the large proportion of breast cancer patients with early-stage, estrogen receptor-positive disease. We sought to understand the impact of receiving genomic recurrence risk estimates on breast cancer patients' well-being and the impact of these patient-reported outcomes on receipt of adjuvant chemotherapy. Participants were 193 women (mean age 57) newly diagnosed with early-stage breast cancer. Women were interviewed before and 2-3 weeks after receiving the RS result between 2011 and 2015. We assessed subsequent receipt of chemotherapy from chart review. After receiving their RS, perceived pros (t = 4.27, P < .001) and cons (t = 8.54, P < .001) of chemotherapy increased from pre-test to post-test, while perceived risk of breast cancer recurrence decreased (t = 2.90, P = .004). Women with high RS tumors were more likely to receive chemotherapy than women with low RS tumors (88 vs. 5 %, OR 0.01, 0.00-0.02, P < .001). Higher distress (OR 2.19, 95 % CI 1.05-4.57, P < .05) and lower perceived cons of chemotherapy (OR 0.50, 95 % CI 0.26-0.97, P < .05) also predicted receipt of chemotherapy. Distressed patients who saw few downsides of chemotherapy received this treatment. Clinicians should consider these factors when discussing chemotherapy with breast cancer patients. PMID:27059031

    Tamoxifen is an effective endocrine treatment for early breast cancer (EBC) but increases the risk of venous thromboembolism. Whether Asian EBC patients (pts) bear the same risk when treated with adjuvant tamoxifen is uncertain. EBC pts diagnosed between 2004 and 2009 were selected from a population database in Taiwan. The pts were followed up from the index date to December 31, 2011 to collect events of deep vein thrombosis (DVT) and pulmonary embolism (PE). Cumulative incidence rates and hazard ratios (HRs) were used to compare the risk between pts treated with and without tamoxifen. In addition, comorbidities were included in an adjusted model of the risk of DVT and PE. A total of 28,029 EBC pts, including 17,843 (63.8 %) in the tamoxifen group and 10,155 (36.2 %) in the nontamoxifen group, were analyzed. The 7-year cumulative incidence rates for DVT and PE were 2.58 and 0.32 % in the tamoxifen group and 2.51 and 0.32 % in the nontamoxifen group (P = 0.92 for DVT, P = 0. 65 for PE), respectively. The HR for the nonadjusted and adjusted models showed no differences in DVT and PE risks between the tamoxifen and nontamoxifen groups. The uterine cancer risk was significantly increased in the pts receiving tamoxifen (adjusted HR = 2.79, P < 0.001), suggesting tamoxifen compliance. The risks of developing DVT and PE are not increased in Asian EBC pts receiving adjuvant tamoxifen. Ethnicity differences should be considered when discussing optimal endocrine treatments with EBC pts.

    The objective of the study was to assess factors associated with treatment satisfaction among patients receiving antihypertensive therapy. A weighted cross-sectional online survey was conducted with hypertensive patients participating in a chronic disease panel in the US. Patients on monotherapy with medications from the following classes were identified: ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), beta blockers (BBs), calcium channel blockers (CCBs), and diuretics. The control group included patients without treatment. Pairwise comparisons between groups were conducted for factors that may affect patients' satisfaction. The study population had a mean age of 54.7+/-14.2 years and was 56.7% female. Participants with blood pressure (BP) controlled to JNC 7 guidelines were more satisfied with their medication than those with uncontrolled BP (90.3 vs 71.5%, P<0.05). Patients who had not experienced adverse events had higher satisfaction than patients experiencing adverse events (90.9 vs 75.8%, P<0.05). The most frequently self-reported adverse events were frequent urination, sexual dysfunction, and fatigue ranging from 7.0 to 9.6% across classes. The adverse event rates differed by class and were lowest among the ARBs. Patients on ARBs were the most likely to have switched from a previous antihypertensive class as compared to other classes (57.1% ARBs vs 49.8% ACEIs, 38.7% diuretics, 36.3% CCBs, and 31.7% BBs). Physician recommendation was the most common reason for switching. In conclusion, the ability to effectively treat hypertension depends upon a patient's satisfaction with antihypertensive therapy, which may be improved by achieving BP control and minimizing the occurrence of adverse events.

    Purpose The goal of this study was to characterize changes in daily fatigue in women undergoing chemotherapy for breast cancer. We examined whether there are subgroups of patients with distinct fatigue trajectories and explored potential psychosocial and biomedical predictors of these subgroups. Methods Participants were 77 women with breast cancer receiving adjuvant chemotherapy with AC-T (2-week cycle) and TC or TCH (3-week cycle) regimens. They completed 28 daily ratings online using an adapted version of the Patient-Reported Outcomes Measurement Information System (PROMIS®) fatigue instrument. Results Both regimens followed an “inverted-U shaped” fatigue pattern over approximately 2 weeks. Growth mixture modeling identified three patient subgroups with distinct trajectories. Fatigue scores in the “low fatigue” group (23%) increased following the infusion and quickly abated. The “transient fatigue” (27%) group had a very pronounced increase. Patients in the “high fatigue” (50%) group reported consistently elevated fatigue with a relatively small increase. Demographic and medical variables were not associated with fatigue trajectory. Patients in the “high fatigue” group reported significantly poorer physical, emotional, and social functioning, poorer general health, and more depressed mood than patients in the “low fatigue” group. The “transient fatigue” group reported significantly better physical and social functioning than the “high fatigue” group, but emotional distress and depression similar to the “high fatigue” group. Conclusions The identification of patient subgroups with distinct fatigue trajectories during chemotherapy is an essential step for developing preventative strategies and tailored interventions. Our results suggest that different trajectories are associated with patients’ psychosocial and general health. PMID:25876159

    Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor in gastrointestinal tracts; however, the synchronous or metachronous coexistence of GIST with additional primary malignancy is not common.Here, we present an unusual case of gastric GIST with metachronous primary lung adenocarcinoma diagnosed during his adjuvant treatment with oral receptor tyrosine kinase inhibitor imatinib mesylate (400 mg daily). After 6-month use of imatinib, the patient suffered from dry cough and dyspnea. Subsequent lung biopsy demonstrated adenocarcinoma with diffuse interstitial changes.Our research emphasizes the possibility of an additional primary tumor with GIST, and reminds the clinicians to strengthen the surveillance of the additional cancer during the follow-up of GIST patients.

    In Taiwan, oral cancer has becomes the fastest growth male cancer disease due to the betel nut chewing habit combing with smoking and alcohol-drinking lifestyle of people. In order to eliminate the systemic phototoxic effect of 5-aminolevulinic acid (ALA), this study was designed to use a topical ALA-mediated PDT for treatment of DMBA-induced hamster buccal pouch precancerous lesions. DMBA was applied to one of the buccal pouches of hamsters thrice a week for 10 to 12 weeks. Cancerous lesions were induced and proven by histological examination. These DMBA-induced cancerous lesions were used for testing the efficacy of topical ALA-mediated PDT. Before PDT, fluorescence spectroscopy was used to determine when ALA reached its peak level in the lesional epithelial cells after topical application of ALA gel. We found that ALA reached its peak level in precancerous lesions about 2.5 hrs after topical application of ALA gel. The cancerous lesions in hamsters were then treated with topical ALA -mediated PDT with light exposure dose of 150 J/cm2 using LED 635 nm fiber-guided light device. Visual examination demonstrated that adjuvant topical ALA -mediated PDT group has shown better therapeutic results in compared to those of non-adjuvant topical ALA-mediated PDT group for DMBA-induced hamster buccal pouch precancerous lesions.

    Curcumin is a complementary therapy that may be helpful for the treatment of psoriasis due to its anti-inflammatory, antiangiogenic, antioxidant, and antiproliferative effects. In the present study we performed a randomized, double-blind, placebo-controlled clinical trial to assess the effectiveness of a bioavailable oral curcumin in the treatment of psoriasis. Sixty-three patients with mild-to-moderate psoriasis vulgaris (PASI < 10) were randomly divided into two groups treated with topical steroids and Meriva, a commercially available lecithin based delivery system of curcumin, at 2 g per day (arm 1), or with topical steroids alone (arm 2), both for 12 weeks. At the beginning (T0) and at the end of the therapy (T12), clinical assessment and immunoenzymatic analysis of the serum levels of IL-17 and IL-22 were performed. At T12, both groups achieved a significant reduction of PASI values that, however, was higher in patients treated with both topical steroids and oral curcumin than in patients treated only with topical steroids. Moreover, IL-22 serum levels were significantly reduced in patients treated with oral curcumin. In conclusion, curcumin was demonstrated to be effective as an adjuvant therapy for the treatment of psoriasis vulgaris and to significantly reduce serum levels of IL-22. PMID:26090395

    Purpose Splenomegaly is a clinical surrogate of oxaliplatin-induced sinusoidal obstruction syndrome (SOS). We investigated development of splenomegaly and its association with treatment outcome and genetic polymorphisms following adjuvant 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) in colorectal cancer (CRC) patients. Materials and Methods Splenomegaly was determined by spleen volumetry using computed tomography images obtained before initiation of chemotherapy and after completion of adjuvant FOLFOX in CRC patients. Ten genetic polymorphisms in 4 SOS-related genes (VEGFA, MMP9, NOS3, and GSTP1) were analyzed using DNA from peripheral blood mononuclear cells. Results Of 124 patients included, increase in spleen size was observed in 109 (87.9%). Median change was 31% (range, –42% to 168%). Patients with splenomegaly had more severe thrombocytopenia compared to patients without splenomegaly during the chemotherapy period (p < 0.0001). The cumulative dose of oxaliplatin and the lowest platelet count during the chemotherapy period were clinical factors associated with splenomegaly. However, no significant associations were found between genetic polymorphisms and development of splenomegaly. Disease-free survival was similar regardless of the development of splenomegaly. Conclusion Splenomegaly was frequently observed in patients receiving adjuvant FOLFOX and resulted in more severe thrombocytopenia but did not influence treatment outcome. Examined genetic polymorphisms did not predict development of splenomegaly. PMID:26790967

    Purpose: The aim of our study was to evaluate patterns and predictors of early biochemical recurrence (eBCR) after radical prostatectomy (RP) and adjuvant radiation therapy (aRT) in order to identify which individuals might benefit from additional treatments. Methods and Materials: We evaluated 390 patients with pT{sub 3}N{sub 0} prostate cancer (PCa) receiving RP and aRT at 6 European centers between 1993 and 2006. Patients who were free from BCR at <2 years' follow-up were excluded. This resulted in 374 assessable patients. Early BCR was defined as 2 consecutive prostate-specific antigen (PSA) test values >0.2 ng/mL within 2 or 3 years after aRT. Uni- and multivariable Cox regression analyses predicting overall and eBCR after aRT were fitted. Covariates consisted of preoperative PSA results, surgical margins, pathological stage, Gleason score, and aRT dose. Results: Overall, 5- and 8-year BCR-free survival rates were 77.1% and 70.8%, respectively. At a median follow-up of 86 months after aRT, 33 (8.8%) and 55 (14.6%) men experienced BCR within 2 or 3 years after aRT, respectively. In multivariable analyses, Gleason scores of 8 to 10 represented the only independent predictor of eBCR after aRT (all, P≤.01). The risk of BCR was significantly higher in patients with a Gleason score of 8 to 10 disease than in those with Gleason 2 to 6 within 24 months after treatment, after adjusting for all covariates (all, P≤.04). However, given a 24-month BCR free period, the risk of subsequent BCR for men with poorly differentiated disease was equal to that of men with less aggressive disease (all, P≥.3). Conclusions: High Gleason score represents the only predictor of eBCR after RP and aRT in patients affected by pT{sub 3}N{sub 0} PCa. Given the association between early PSA recurrence, clinical progression, and mortality, these patients might be considered candidates for adjuvant medical therapy and/or prophylactic whole-pelvis radiation therapy in addition to a

    Purpose Although the incidence and mortality of colon cancer in the United States has declined over the past two decades, blacks have worse outcomes than whites. Variations in treatment may contribute to mortality differentials. Methods Patients diagnosed with stage III colon cancer were randomly sampled from the SEER program from the years 1990, 1991, 1995, 2000, 2005, and 2010. Patients were categorized as non-Hispanic white (n = 835) or black (n = 384). Treatment data were obtained from a review of the medical records, and these data were verified through contact with the original treating physicians. Log-binomial regression models were used to estimate the association between race and receipt of adjuvant chemotherapy. Effect modification by insurance was assessed with use of single referent models. Results Receipt of adjuvant chemotherapy among both white and black patients increased from the period encompassing the years 1990 and 1991 (white, 58%; black, 45%) to the year 2005 (white, 72%; black, 71%) and then decreased in the year 2010 (white, 66%; black, 57%). There were marked racial disparities in the time period of 1990 to 1991 and again in 2010, with black patients less likely to receive adjuvant chemotherapy as compared with white patients (risk ratio [RR], .82; 95% CI, .72 to .93). For black patients, receipt of adjuvant chemotherapy did not differ across insurance categories (RR for private insurance, .80; 95% CI, .69 to .93; RR for Medicare, .84; 95% CI, .69 to 1.02; and RR for Medicaid, .84; 95% CI, .69 to 1.02), although a larger proportion had Medicaid in all years of the study as compared with white patients. Conclusion The chemotherapy differential narrowed after the time period of 1990 to 1991, but our findings suggest that the disparity reemerged in 2010. Recent decreases in chemotherapy use may be due, in part, to the economic downturn and an increase in Medicaid coverage. PMID:26150445

    The treatment of patients with colorectal liver metastasis has improved significantly and first line therapy is often combined chemotherapy and bevacizumab, although it is unknown who responds to this regimen. Colorectal liver metastases grow in different histological growth patterns showing differences in angiogenesis. To identify possible response markers, histological markers of angiogenesis were assessed. Patients who underwent resection of colorectal liver metastasis at Rigshospitalet, Copenhagen, Denmark from 2007 to 2011 were included (n = 254) including untreated and patients treated with chemotherapy or chemotherapy plus bevacizumab. The resected liver metastases were characterised with respect to growth pattern, endothelial and tumour cell proliferation as well as microvessel density and tumour regression. Tumour regression grade of liver metastases differed significantly between untreated/chemotherapy treated patients in comparison to chemotherapy plus bevacizumab treated patients (both p < 0.0001). Microvessel density was decreased in liver metastases from patients treated with bevacizumab in comparison to those from untreated/chemotherapy-treated patients (p = 0.006/p = 0.002). Tumour cell proliferation assessed by Ki67 expression correlated to a shorter recurrence free survival in the total patient cohort. In conclusion, liver metastases from patients treated with neo-adjuvant chemotherapy and bevacizumab had significantly lower microvessel densities and tumour regression grades when compared to liver metastases from untreated or chemotherapy treated patients. This may indicate that bevacizumab treatment results in altered vascular biology and tumour viability, with possible tumour reducing effect.

    Clinical surveys show a continuous increase of antimicrobial resistance related to the frequency of the administrated medication. The antimicrobial photodynamic therapy (aPDT) is an effective adjuvant to reduce the need of antibiotics in dentistry, especially in periodontics. The antimicrobial effect of lightactivated photosensitizers in periodontics is demonstrated in clinical studies and case reports. Indocyanine green (ICG) as a new adjuvant shows the high potential of antiphlogistic and antimicrobial effects in combination with laser-light activation. In trying to answer the question of just how far the influence of temperature is acting on bacteria, this study was carried out. The influences of ICG at different concentrations (0.01 up to 1 mg/ml) in combination with a culture medium (brain-heart-infusion) and a bacteria culture (Streptococcus salivarius) at different optical densities (OD600 0.5 and 0.1) were investigated under laser-light activation. Laser activation was carried out with diode laser at 810 nm and two different power settings (100 mW/300 mW). The pulse repetition rate was 2 kHz. Taking account of the fiber diameter, distance and spot size on the sample surface, the applicated intensities were 6.2 and 18.7 W/cm2. Total irradiation time was 20 s for all meaurements. Transmitted laser power and temperature increase in the culture medium as well as in the bacteria culture were determined. Additionally the influence of ICG regarding bacterial growth and bactericidal effect was investigated in the bacteria culture without laser irradiation. Without laser, no bactericidal effect of ICG was observed. Only a bacteriostatic effect could be proved. In dependence of the ICG concentration and the applied intensities a temperature increase of ΔT up to 80°C was measured.

    Cellular immunity was assessed in 85 patients with head and neck cancer with monoclonal antibodies to lymphocyte surface antigens that identify total T cells, helper cells, and suppressor cells. The control group consisted of 22 healthy volunteers. Nine patients who had surgical procedures for benign diseases were also studied. Compared with the controls, the patients with cancer who received radiation therapy had a significant decrease in total lymphocytes, T cells, helper cells, suppressor cells, and decreased helper/suppressor cell ratio. Significant decreases in lymphocyte subpopulations were not detected in patients tested before treatment or in patients treated with surgery alone. The immune deficits observed were prolonged in duration, with some present in the patients studied up to 11 years after radiation therapy. This long-lasting immune depression may have relevance to tumor recurrences and second primaries in patients with head and neck cancer treated by radiation therapy and to attempts at increasing cure rates with adjuvant agents that improve immune reactivity.

    Objectives Criteria for the selection of patients for adjuvant chemotherapy in intrahepatic cholangiocarcinoma (IHCC) are lacking. Some authors advocate treating patients with lymph node (LN) involvement; however, nodal assessment is often inadequate or not performed. This study aimed to identify surrogate criteria based on characteristics of the primary tumour. Methods A total of 58 patients who underwent resection for IHCC between January 2000 and January 2010 at any of three institutions were identified. Primary outcome was overall survival (OS). Results Median OS was 23.0 months. Median tumour size was 6.5 cm and the median number of lesions was one. Overall, 16% of patients had positive margins, 38% had perineural invasion (PNI), 40% had lymphovascular invasion (LVI) and 22% had LN involvement. A median of two LNs were removed and a median of zero were positive. Lymph nodes were not sampled in 34% of patients. Lymphovascular and perineural invasion were associated with reduced OS [9.6 months vs. 32.7 months (P= 0.020) and 10.7 months vs. 32.7 months (P= 0.008), respectively]. Lymph node involvement indicated a trend towards reduced OS (10.7 months vs. 30.0 months; P= 0.063). The presence of either LVI or PNI in node-negative patients was associated with a reduction in OS similar to that in node-positive patients (12.1 months vs. 10.7 months; P= 0.541). After accounting for adverse tumour factors, only LVI and PNI remained associated with decreased OS on multivariate analysis (hazard ratio 4.07, 95% confidence interval 1.60–10.40; P= 0.003). Conclusions Lymphovascular and perineural invasion are separately associated with a reduction in OS similar to that in patients with LN-positive disease. As nodal dissection is often not performed and the number of nodes retrieved is frequently inadequate, these tumour-specific factors should be considered as criteria for selection for adjuvant chemotherapy.

    For the first time, we discovered a small proportion of aqueous fraction from Saw Palmetto apart from the fatty acid-rich fraction exhibited pharmacological activity. Therefore, this study aims to explore the anti-tumor potential of red pigmented aqueous fraction of Saw Palmetto, NYG on human hepatocellular carcinoma and its possible targets. Subcutaneous xenograft and orthotopic implantation models of HCC were used to evaluate the tumor inhibitory effect of NYG. Human hepatocellular carcinoma (HCC) cell lines and human umbilical vein endothelial cells (HUVEC) were used as in vitro model. The mRNA expression was conducted by qPCR. Protein expression was monitored by immunoblotting and immunohistochemistry. Cell migration and blood vessel formation were determined by chamber assay and tube formation assay, respectively. Significant tumor inhibition of NYG in dose-dependent manner was observed on subcutaneous xenograft and orthotopic HCC model. NYG has no direct action on cell viability or VEGF secretion of HCC cells. However, NYG reduced in vitro migration and vessel formation activities of HUVEC cells, as well as in vivo intratumoral neovascularization. NYG attenuated extracellular signal-regulated kinases (ERK) activation in endothelial cells, which may be associated with the suppression of migration and tube formation of HUVEC. NYG suppressed tumor expansion of HCC via inhibiting neovascularization, and may be potential adjuvant treatment for HCC. PMID:27527161

    Purpose: To analyze the outcome of adjuvant chemoradiotherapy for patients with distal common bile duct (CBD) cancer who underwent curative surgery, and to identify the prognostic factors for these patients. Methods and Materials: Between January 1991 and December 2002, 38 patients with adenocarcinoma of the distal CBD underwent curative resection followed by adjuvant chemoradiotherapy. There were 27 men and 11 women, and the median age was 60 years (range, 34-73). Adjuvant radiotherapy was delivered to the tumor bed and regional lymph nodes up to 40 Gy at 2 Gy/fraction with a 2-week planned rest. Intravenous 5-fluorouracil (500mg/m{sup 2}/day) was given on day 1 to day 3 of each split course. The median follow-up period was 39 months. Results: The 5-year overall survival rate of all patients was 49.1%. On univariate analysis, only histologic differentiation (p = 0.0005) was associated with overall survival. Tumor size ({<=}2cm vs. >2cm) had a marginally significant impact on the treatment outcome (p = 0.0624). However, there was no difference in overall survival rates between T3 and T4 tumors (p = 0.6189), for which the main determinants were pancreatic and duodenal invasion, respectively. On multivariate analysis, histologic differentiation (p = 0.0092) and tumor size (p = 0.0046) were independent risk factors for overall survival. Conclusions: Long-term survival can be expected in patients with distal CBD cancer undergoing curative surgery and adjuvant chemoradiotherapy. Histologic differentiation and tumor size were significant prognostic factors predicting overall survival, whereas duodenal invasion was not. This finding suggests the need for further refinement in tumor staging.

    Purpose: Radiotherapy (RT) and chemotherapy may prolong survival in older patients (age {>=}70 years) with glioblastoma multiforme (GBM), although the survival benefits remain poor. This Phase II multicenter study was designed to evaluate the efficacy and safety of an abbreviated course of RT plus concomitant and adjuvant temozolomide (TMZ) in older patients with GBM. Patients and Methods: Seventy-one eligible patients 70 years of age or older with newly diagnosed GBM and a Karnofsky performance status {>=}60 were treated with a short course of RT (40 Gy in 15 fractions over 3 weeks) plus TMZ at the dosage of 75 mg/m{sup 2} per day followed by 12 cycles of adjuvant TMZ (150-200 mg/m{sup 2} for 5 days during each 28-day cycle). The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival and toxicity. Results: The Median OS was 12.4 months, and the 1-year and 2-year OS rates were 58% and 20%, respectively. The median and 1-year rates of progression-free survival were 6 months and 20%, respectively. All patients completed the planned programme of RT. Grade 3 or 4 adverse events occurred in 16 patients (22%). Grade 3 and 4 neutropenia and/or thrombocytopenia occurred in 10 patients (15%), leading to the interruption of treatment in 6 patients (8%). Nonhematologic Grade 3 toxicity was rare, and included fatigue in 4 patients and cognitive disability in 1 patient. Conclusions: A combination of an abbreviated course of RT plus concomitant and adjuvant TMZ is well tolerated and may prolong survival in elderly patients with GBM. Future randomized studies need to evaluate the efficacy and toxicity of different schedules of RT in association with chemotherapy.

    Background: The American College of Surgeons Oncology Group sought to confirm the efficacy of a novel interferon-based chemoradiation regimen in a multicenter phase II trial. Patients and methods: Patients with resected (R0/R1) adenocarcinoma of the pancreatic head were treated with adjuvant interferon-alfa-2b (3 million units s.c. on days 1, 3, and 5 of each week for 5.5 weeks), cisplatin (30 mg/m2 i.v. weekly for 6 weeks), and continuous infusion 5-fluorouracil (5-FU; 175 mg·m2/day for 38 days) concurrently with external-beam radiation (50.4 Gy). Chemoradiation was followed by two 6-week courses of continuous infusion 5-FU (200 mg·m2/day). The primary study end point was 18-month overall survival from protocol enrollment (OS18); an OS18 ≥65% was considered a positive study outcome. Results: Eighty-nine patients were enrolled. Eighty-four patients were assessable for toxicity. The all-cause grade ≥3 toxicity rate was 95% (80 patients) during therapy. No long-term toxicity or toxicity-related deaths were noted. At 36-month median follow-up, the OS18 was 69% [95% confidence interval (CI) 60% to 80%]; the median disease-free survival and overall survival were 14.1 months (95% CI 11.0–20.1 months) and 25.4 months (95% CI 23.4–34.1 months), respectively. Conclusions: Notwithstanding promising multi-institutional efficacy results, further development of this regimen will require additional modifications to mitigate toxic effects. PMID:20670978

    Most chemotherapy treatments induce DNA damage in the exposed patients. Using the comet assay and peripheral blood mononuclear cells (PBMC), we have quantified this induced DNA damage and studied its relationship with GSTM1 and GSTT1 polymorphisms, and clinical parameters. For this purpose, 29 Caucasian women, breast cancer patients under CMF or CEF adjuvant chemotherapy were included in the study. The clinical parameters considered were (i) therapies side effects, like haematological and biochemical toxicities, (ii) prognostic and predictive factors, like hormonal receptor expression, tumour differentiation degree, sickness stage, and nodal status, and (iii) the effectiveness of the chemotherapy measured as five years relapse probability. The results were also related to the confounding factor age. Comet assay results indicate that 13 patients were characterised by absence of induced DNA strand breaks, and 16 patients presented induced DNA strand breaks along the treatment. Relationships between comet variables and clinical parameters, found with principal component analysis, correlations, one-way ANOVA and multivariate logistic regression analyses revealed that: (1) baseline levels of DNA damage are related to GSTM1 genotype and to hormonal receptor expression; (2) GSTM1 genotype also influences comet results after chemotherapy, as it does the AST level; (3) the tail moment values of the cycle 6.1 and the sickness stage might predict cancer relapse at five years: for the Stage, OR = 13.8 (IIB versus I+IIA), 95% CI 0.80-238.97, and for 6.1 cycle TM, OR = 1.3, 95%, CI 0.97-1.79, with a potential model (10* Stage (I-IIA = 0, IIB = 1) + 6.1 cycle), that has a good predictive capacity, with an area under ROC curve of 0.872 (CI 0.62-1.00). To our knowledge, this is the first time such a predictive value is found for the comet assay. Nevertheless, before the comet assay could be used as a tool for oncologists, this relationship should be confirmed in more patients, and

    It is unknown whether racial differences exist in adjuvant chemotherapy initiation among women with similar oncotype DX (ODX) risk scores. We examined whether adjuvant chemotherapy initiation varied by race. Data come from the Phase III, Carolina Breast Cancer Study, a longitudinal, population-based study of North Carolina women diagnosed with breast cancer between 2008 and 2014. We used modified Poisson regression and report adjusted relative risk (aRR) and 95% confidence intervals (95%CI) to estimate the association between race and adjuvant chemotherapy initiation across ODX risk groups among women who received the test (n = 541). Among women who underwent ODX testing, 54.2, 37.5, and 8.3% of women had tumors classified as low-, intermediate-, and high-risk groups, respectively. We observed no racial variation in adjuvant chemotherapy initiation. Increasing ODX risk score (aRR = 1.39, 95%CI = 1.22, 1.58) and being married (aRR = 2.92, 95%CI = 1.12, 7.60) were independently associated with an increased likelihood of adjuvant chemotherapy in the low-risk group. Among women in the intermediate-risk group, ODX risk score (aRR = 1.15, 95%CI = 1.11, 1.20), younger age (aRR = 1.95, 95%CI = 1.35, 2.81), larger tumor size (aRR = 1.70, 95%CI = 1.22, 2.35), and higher income were independently associated with increased likelihood of adjuvant chemotherapy initiation. No racial differences were found in adjuvant chemotherapy initiation among women receiving ODX testing. As treatment decision-making becomes increasingly targeted with the use of genetic technologies, these results provide evidence that test results may drive treatment in a similar way across racial subgroups.

    Pancreatic adenocarcinoma is one of the most aggressive human malignancies, ranking 4th among causes for cancer-related death in the Western world including the United States. Surgical resection offers the only chance of cure, but only 15 to 20 percent of cases are potentially resectable at presentation. Different studies demonstrate and confirm that advanced pancreatic cancer is among the most complex cancers to treat and that these tumors are relatively resistant to chemotherapy and radiotherapy. Currently there is no consensus around the world on what constitutes “standard” adjuvant therapy for pancreatic cancer. This controversy derives from several studies, each fraught with its own limitations. Standards of care also vary somewhat with regard to geography and economy, for instance chemo-radiotherapy followed by chemotherapy or vice versa is considered the optimal therapy in North America while chemotherapy alone is the current standard in Europe. Regardless of the efforts in adjuvant and neoadjuvant improved therapy, the major goal to combat pancreatic cancer is to find diagnostic markers, identifying the disease in a pre-metastatic stage and making a curative treatment accessible to more patients. In this review, authors examined the different therapy options for advanced pancreatic patients in recent years and the future directions in adjuvant and neoadjuvant treatments for these patients.

    The Southwest Oncology Group conducted a pilot study in patients who had had total clinical resection of cancer of the colon and had a high risk of recurrence (Duke's C); the purpose of the study was to determine the toxic effects of intra-arterial chemotherapy combined with hepatic radiotherapy, in anticipation of their potential use in an adjuvant groupwide protocol. The treatment plan included intra-arterial chemotherapy with mitomycin (3 mg/m2) on Days 1, 4, 35, and 38 by slow intra-arterial push and 5-FU (1000 mg/m2) on Days 1-4 and 35-38 by continuous 96-hour infusion. Radiation therapy was begun on Day 8 of therapy and consisted of 1950 rads in 13 fractions over 2 1/2 weeks. Nineteen patients have been studied. Of 13 fully evaluable patients, two have relapsed in the liver. Eleven patients have developed significant, persistent liver enzyme elevations, and one patient has died from therapy-related liver failure. Combined radiotherapy and intra-arterial chemotherapy may result in significant chronic liver damage, and caution should be exercised in future adjuvant trials.

    Summary Canadian women with breast cancer may choose breast conserving therapy as their course of treatment, requiring both breast conserving surgery and adjuvant radiation therapy. However, more than 15% of Canadian women fail to receive the appropriate radiation therapy, putting them at increased risk for recurrence. Age, distance from their radiation therapy centre and stage of disease affect patients’ likelihood of receiving prescribed radiation therapy. We propose a nomogram that allows physicians to predict which patients will and will not receive radiation. This nomogram, once validated, could be used to guide decision making when choosing between breast conserving therapy and mastectomy as the treatment course and thereby change the practice of breast cancer management.

    Purpose: New radiation therapy modalities have broadened treatment options for older women with breast cancer, but it is unclear how clinical factors, geographic region, and physician preference affect the choice of radiation therapy modality. Methods and Materials: We used the Surveillance, Epidemiology, and End Results-Medicare database to identify women diagnosed with stage I-III breast cancer from 1998 to 2007 who underwent breast-conserving surgery. We assessed the temporal trends in, and costs of, the adoption of intensity modulated radiation therapy (IMRT) and brachytherapy. Using hierarchical logistic regression, we evaluated the relationship between the use of these new modalities and patient and regional characteristics. Results: Of 35,060 patients, 69.9% received conventional external beam radiation therapy (EBRT). Although overall radiation therapy use remained constant, the use of IMRT increased from 0.0% to 12.6% from 1998 to 2007, and brachytherapy increased from 0.7% to 9.0%. The statistical variation in brachytherapy use attributable to the radiation oncologist and geographic region was 41.4% and 9.5%, respectively (for IMRT: 23.8% and 22.1%, respectively). Women undergoing treatment at a free-standing radiation facility were significantly more likely to receive IMRT than were women treated at a hospital-based facility (odds ratio for IMRT vs EBRT: 3.89 [95% confidence interval, 2.78-5.45]). No such association was seen for brachytherapy. The median radiation therapy cost per treated patient increased from $5389 in 2001 to $8539 in 2007. Conclusions: IMRT and brachytherapy use increased substantially from 1998 to 2007; overall, radiation therapy costs increased by more than 50%. Radiation oncologists played an important role in treatment choice for both types of radiation therapy, whereas geographic region played a bigger role in the use of IMRT than brachytherapy.

    Gastric cancer remains one of the most common malignancies worldwide. Despite the significant advances in surgical treatment and multimodality strategies, prognosis has modestly improved over the last two decades. Locoregional relapse remains one of the main issues and the combined chemoradiation treatment seems to be one of the preferred approaches. However, more than ten years after the hallmark INT-0116 trial, minimal progress has been made both in terms of effectiveness and toxicity. Moreover, new regimens added to combined therapy failed to prove favourable results. Herein, we attempt a thorough literature review comparing pros and cons of all relative studies and potential bias, targeting well-designed future approaches. PMID:26101524

    Purpose: To evaluate follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels after postoperative chemoradiation in men with rectal cancer. Methods and Materials: Forty-three men with rectal cancer had baseline and postchemoradiation FSH, LH, and testosterone measured. Adjuvant chemoradiation consisted of two 5-day cycles of bolus 5-fluorouracil (5-FU) every 4 weeks at a dose of 500 mg/m{sup 2}/d followed by concurrent chemoradiation followed by two additional 5-day cycles of 5-FU at a dose of 450 mg/m{sup 2}/d. Continuous-infusion 5-FU at 225 mg/m{sup 2}/d was given during radiation. Pelvic radiation consisted of a three- or four-field technique with a median dose of 54.0 Gy in 30 fractions. Results: Median follow-up was 6.1 years. Mean baseline FSH levels increased from 5.3 to a peak of 23.9 IU/L (p < 0.001) 13-24 months after chemoradiation. Mean baseline LH levels increased from 4.3 to a peak of 8.5 IU/L (p < 0.001) within 6 months after chemoradiation. Mean testosterone levels decreased from 15.4 nmol/L at baseline to 8.0 nmol/L more than 4 years after chemoradiation. Mean testosterone to mean LH ratio decreased from 4.4 at baseline to 1.1 after 48 months posttreatment, suggesting a continued decrease in Leydig cell function with time. Testicular dose was measured in 5 patients. Median dose was 4 Gy (range, 1.5-8.9 Gy). Conclusions: Chemoradiation in men with rectal cancer causes persistent increases in FSH and LH levels and decreases in testosterone levels.

    Purpose: This study was undertaken to determine whether there was an increased risk of second malignancies (SM), particularly lung cancer, in early stage breast cancer patients treated with the addition of nodal fields to breast and/or chest wall radiation therapy (RT). Materials and Methods: Subjects were stage I/II female breast cancer patients 20 to 79 years of age, diagnosed between 1989 and 2005 and treated with adjuvant RT at our institution. Patients were included if they survived and did not have SM within 3 years of diagnosis. Standardized incidence ratios (SIR) with 95% confidence intervals (CI) were calculated to compare SM incidence to cancer incidence in the general sex- and age-matched populations. Secondary malignancy risks in patients treated with local RT (LRT) to the breast/chest wall were compared to those in patients treated with locoregional RT (LRRT) to the breast/chest wall and regional nodes, using multivariate regression analysis (MVA) to account for covariates. Results: The cohort included 12,836 patients with a median follow-up of 8.4 years. LRRT was used in 18% of patients. The SIR comparing patients treated with LRT to the general population was 1.29 (CI: 1.21-1.38). No statistically significant increased incidence of in-field malignancies (SIR, 1.04; CI: 0.87-1.23) and lung cancers (SIR, 1.06; CI: 0.88-1.26) was detected. The SIR comparing patients treated with LRRT to the general population was 1.39 (CI: 1.17-1.64). No statistically significant increased incidence of in-field malignancies (SIR, 1.26; CI: 0.77-1.94) and lung cancers (SIR, 1.27; CI: 0.76-1.98) was detected. On MVA comparing LRRT to LRT, the adjusted hazard ratio was 1.20 for in-field malignancies (CI: 0.68-2.16) and 1.26 for lung cancer (CI: 0.67-2.36). The excess attributable risk (EAR) to regional RT was 3.1 per 10,000 person years (CI: −8.7 to 9.9). Conclusions: No statistically significant increased risk of second malignancy was detected after LRRT relative to

    The objective of this study was to evaluate the safety, effectiveness and functional outcomes of intraoperative radiotherapy (IORT) followed by intensity-modulated radiation therapy (IMRT) in locally advanced stage tumours involving the middle ear. Data on 13 consecutive patients treated for malignant tumor of external auditory canal involving the middle ear were retrospectively reviewed. Median follow-up was 33 months (range 6-133). Five (38%) patients were stage III and 8 (62%) were Stage IV according to the University of Pittsburgh staging system. Lateral temporal bone resection (LTBR) was performed in all cases. LTBR was associated with parotidectomy in 5 (38%) cases, and with neck dissection and parotidectomy in 6 (46%) cases. No patients had gross residual tumour. Surgical treatment was followed by IORT (12 Gy) and IMRT (50 Gy). Adjuvant chemotherapy was used in 4 (30%) cases. Preoperative and postoperative audiometric tests were performed to assess hearing loss. 5-year local-control (LC), 5-year distant-metastasis (DM), 5-year disease-free-survival (DFS) and 5-year overall-survival (OS) were calculated with Kaplan-Meyer method. Significant changes in bone conduction were reported after treatment. Partial flap necrosis was the only early complication observed in three (23%) cases, while meningeal fistula was seen in one (7.6%) case as a late complication. The 5-year LC-rate was 68%. The 5-year DM-rate was 90%. The 5-year DFS-rate was 61%. The 5-year OS-rate was 69%. IORT followed by IMRT for the treatment of advanced external auditory canal and middle ear tumours seems to be safe. No intraoperative death was reported. IORT may reduce the postoperative irradiation of remnant tissue obtaining the same full dose on the tumour bed. No complications of the residual external ear were observed. Detriment of neurosensory hearing may be expected. Future studies are required to confirm the benefit of this procedure in the ear.

    Cancer therapies based on T cells have shown impressive clinical benefit. In particular, immune checkpoint blockade therapies with anti-CTLA-4 and anti-PD-1/PD-L1 are causing dramatic tumor shrinkage and prolonged patient survival in a variety of cancers. However, many patients do not benefit, possibly due to insufficient spontaneous T cell reactivity against their tumors and/or lacking immune cell infiltration to tumor site. Such tumor-specific T cell responses could be induced through anti-cancer vaccination; but despite great success in animal models, only a few of many cancer vaccine trials have demonstrated robust clinical benefit. One reason for this difference may be the use of potent, effective vaccine adjuvants in animal models, vs. the use of safe, but very weak, vaccine adjuvants in clinical trials. As vaccine adjuvants dictate the type and magnitude of the T cell response after vaccination, it is critical to understand how they work to design safe, but also effective, cancer vaccines for clinical use. Here we discuss current insights into the mechanism of action and practical application of vaccine adjuvants, with a focus on peptide-based cancer vaccines. PMID:27660710

    The cervical cancer is one of the most common malignancies. Worldwide 500,000 women a year become ill from cervical cancer. The aim of the study was to establish the role of adjuvant radiotherapy in patients with IB1 cervical cancer in terms of disease free survival. Between 2002-2012, 132 patients diagnosed as IB1 stage according to FIGO criteria were enrolled in the study. Depending on the administered therapy the patients were divided into two groups--Group 1-93 patients were treated surgically and with adjuvant radiotherapy and Group 2--39 patients were treated surgically without adjuvant radiotherapy Surgery was radical hysterectomy class III and pelvic or paraaortic lymph node dissection(in cases of bulky paraaortic nodes), and adjuvant RT-telegamma therapy(TGT) in dose 52 Gy. The frequency of recurrence in a Group I (surgery and TGT) is 9.7%. Tree and five years disease free survival (DFS) is 88%. The frequency of recurrence in a Group 2 (surgery without TGT) is 25.6%. Tree and five years DFS respectively are 70% and 65%. In an analysis of oncological results establish that adjuvant TGT after surgery significantly increases DFS. On the other hand the addition of adjuvant TGT increases the patients morbidity Therefore should determine which are the risk factors for the occurrence of relapses and select group of patients who would benefit from adjuvant TGT and the risk of complications in them would be justified.

Depending on the administered therapy the patients were divided into two groups--Group 1-93 patients were treated surgically and with adjuvant radiotherapy and Group 2--39 patients were treated surgically without adjuvant radiotherapy Surgery was radical hysterectomy class III and pelvic or paraaortic lymph node dissection(in cases of bulky paraaortic nodes), and adjuvant RT-telegamma therapy(TGT) in dose 52 Gy. The frequency of recurrence in a Group I (surgery and TGT) is 9.7%. Tree and five years disease free survival (DFS) is 88%. The frequency of recurrence in a Group 2 (surgery without TGT) is 25.6%. Tree and five years DFS respectively are 70% and 65%. In an analysis of oncological results establish that adjuvant TGT after surgery significantly increases DFS. On the other hand the addition of adjuvant TGT increases the patients morbidity Therefore should determine which are the risk factors for the occurrence of relapses and select group of patients who would benefit from adjuvant TGT and the risk of complications in them would be justified.

    Slightly focused high-energy shockwave (HESW) therapy is characterized by a wide focal area, a large therapy zone, easy positioning and less pain during treatment. The objective of this study was to perform for the first time an in vivo test of the slightly focused HESWs for osteoporotic fractures. Bilateral proximal tibial osteotomies were made in 30 ovariectomized (OVX) Sprague-Dawley rats and secured with internal fixation. The osteotomy site in the left tibia was subsequently treated with slightly focused HESWs with the energy flux density of 0.26 mj/mm(2), shock repetition frequency of 1 Hz and 2000 shocks (OVX + HESW group). The contralateral right tibia was not treated and served as the control (OVX group). Roentgenographic examination 2, 4, 6, and 8 weeks after osteotomy showed that HESW treatment accelerated tibia fracture healing in osteoporotic rats. Histological examination 2, 4, and 8 weeks after HESW treatment showed a greater inflammatory reaction in the OVX + HESW group, with more mature collagen and trabeculae than in the OVX group. Micro computer tomography (Micro-CT) scanning after 4 and 8 weeks showed that bone volume (BV), bone volume/tissue volume (BV/TV), mean trabecular thickness (Tb.Th), and mean trabecular number (Tb.N) were about 45.0% and 33.1%, 18.4% and 20.1%, 38.2% and 20.9%, 26.7% and 28.4%, respectively, higher in the treatment group than in the control group (P < 0.05); and the mean trabecular separation (Tb.Sp) was about 16.7% and 27.3% lower in the treatment group (P < 0.05). Four and eight weeks after HESW treatment, the maximum compressive callus endurance was about 72.3% and 25.5%, respectively, higher in the treatment group than in the control group (P < 0.05). These results show that slightly focused HESW therapy has a beneficial effect on osteoporotic tibial fracture healing. Slightly focused HESWs could increase callus endurance, induce bone formation, and improve trabecular bone microarchitecture and biomechanical

    The authors present a case of a 27-year-old multiparous woman, with multiple thrombophilia, whose pregnancy was complicated with deep venous thrombosis requiring placement of a vena cava filter. At 15th week of gestation, following an acute deep venous thrombosis of the right inferior limb, anticoagulant therapy with low-molecular-weight heparin (LMWH) was instituted without improvement in her clinical status. Subsequently, at 18 weeks of pregnancy, LMWH was switched to warfarin. At 30th week of gestation, the maintenance of high thrombotic risk was the premise for placement of an inferior vena cava filter for prophylaxis of pulmonary embolism during childbirth and postpartum. There were no complications and a vaginal delivery was accomplished at 37 weeks of gestation. Venal placement of inferior vena cava filters is an attractive option as prophylaxis for pulmonary embolism during pregnancy. PMID:23781361

    The incidence of new primary cancers was evaluated in 3538 postmenopausal patients who had received surgical treatment for primary breast cancer. Of these patients, 1828 with a low risk of recurrence received no further treatment. High-risk patients were randomly assigned to one of two groups. The first group (n = 846) received postoperative radiotherapy, while the second group (n = 864) received radiotherapy plus tamoxifen at a dose of 30 mg given daily for 48 weeks. The median observation time was 7.9 years. In comparison with the number of new cancers in the general population, the number of new cancers in the three groups was elevated mostly due to a high number of cancers of the contralateral breast and of colorectal cancers in the high-risk groups. The cumulative risk of nonlymphatic leukemia was increased among patients who received postoperative radiotherapy (P = .04). Cancer incidence in the high-risk tamoxifen-treated group relative to that in the high-risk group not treated with tamoxifen was not significant (1.3). No protective effect of tamoxifen on the opposite breast was seen (rate ratio for breast cancer = 1.1), but a tendency to an elevated risk of endometrial cancer was observed (rate ratio = 3.3; 95% confidence interval = 0.6-32.4). Continued and careful follow-up of women treated with tamoxifen is necessary to clarify the potential cancer-suppressive or cancer-promoting effects of this drug.

    The discrepancy between the surgical technique and the type of adjuvant chemotherapy used in clinical trials and patient outcomes in terms of overall survival rates has led to the generation of different adjuvant treatment protocols in distinct parts of the world. The adjuvant treatment recommendation is generally chemoradiotherapy in the United States, perioperative chemotherapy in the United Kingdom and parts of Europe, and chemotherapy in Asia. These options mainly rely on the United States Intergroup-0116, United Kingdom British Medical Research Council Adjuvant Gastric Infusional Chemotherapy, and the Asian Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer and Capecitabine and Oxaliplatin Adjuvant Study in Stomach Cancer trials. However, the benefits were evident for only certain patients, which were not very homogeneous regarding the type of surgery, chemotherapy regimens, and stage of disease. Whether the dissimilarities in survival are attributable to surgical technique or intrinsic biological differences is a subject of debate. Regardless of the extent of surgery, multimodal therapy may offer modest survival advantage at least for diseases with lymph node involvement. Moreover, in the era of individualized treatment for most of the other cancer types, identification of special subgroups comprising those who will derive more or no benefit from adjuvant therapy merits further investigation. The aim of this review is to reveal the historical evolution and future reflections of adjuvant treatment modalities for resected gastric cancer patients. PMID:27190583

    Severe pulmonary embolism often leads to right ventricular failure after surgical embolectomy secondary to ischaemia reperfusion injury and acute lung injury (ALI). Acute right ventricular dysfunction is traditionally treated with inotropes and vasopressors to maintain cardiac output and coronary perfusion as well as selective pulmonary vasodilators to provide right ventricular afterload reduction. We report the first case of utilisation of methylene (MB) in a patient with acute right ventricular failure and vasoplegic shock after surgical pulmonary embolectomy. PMID:20952252

    The aim of this study was to determine whether there are racial/ethnic differences in initiation and timing of adjuvant endocrine therapy (AET) after Medicare Part D drug coverage. We conducted a retrospective cohort study using data from the Surveillance, Epidemiology, and End Results-Medicare-linked data to assess ethnic, socio-demographic, and tumor characteristic variations in the initiation of AET among patients ≥65 with hormone receptor-positive breast cancer in 2007-2009 enrolled in Medicare Part D through 2010. Logistic regression models were performed to assess the association between race/ethnicity and the initiation of tamoxifen, aromatase inhibitors (AIs), and overall AET (tamoxifen or AIs) within the first 12 months of diagnosis. Of the 12,198 women with hormone receptor-positive breast cancer, 74.8 % received AET within 12 months of diagnosis, of which 17.3 % received tamoxifen and 82.8 % received AIs. After controlling for all variables, only Asian women were found to have a greater odds of initiation of overall AET compared to non-Hispanic white women (odds ratio (OR): 1.28, 95 % CI: 1.03-1.58). Hispanic Mexicans and non-Hispanic black patients had a significantly lower odds of tamoxifen initiation (0.70, 0.54-0.91; 0.25, 0.10-0.62). For AI initiation, Hispanic Mexicans and Asians had a higher odds compared to non-Hispanic white women (2.06, 1.34-3.10; 1.33, 1.11-1.61). A suboptimal proportion of women (25.2 %) did not initiate AET within 12 months of diagnosis and therefore did not receive the full benefits of treatment to reduce the risk of breast cancer recurrence and mortality. Racial/ethnic differences in the initiation of tamoxifen and AIs have important implications that require further investigation.

    The purpose of this study was to conduct an exploratory analysis of the START examining the effects of resistance exercise training (RET) and aerobic exercise training (AET) on sarcopenia, dynapenia, and associated quality of life (QoL) changes in breast cancer (BC) patients receiving adjuvant chemotherapy. Participants were randomized to usual care (UC) (n = 70), AET (n = 64), or RET (n = 66) for the duration of chemotherapy. Measures of sarcopenia [skeletal muscle index (SMI)] and dynapenia [upper extremity (UE) and lower extremity (LE) muscle dysfunction (MD)] were normalized relative to age-/sex-based clinical cut-points. QoL was assessed by the Functional Assessment of Cancer Therapy-Anemia (FACT-An) scales. At baseline, 25.5 % of BC patients were sarcopenic and 54.5 % were dynapenic with both conditions associated with poorer QoL. ANCOVAs showed significant differences favoring RET over UC for SMI (0.32 kg/m(2); p = 0.017), UE-MD (0.12 kg/kg; p < 0.001), and LE-MD (0.27 kg/kg; p < 0.001). Chi-square analyses revealed significant effects of RET, compared to UC/AET combined, on reversing sarcopenia (p = 0.039) and dynapenia (p = 0.019). The reversal of sarcopenia was associated with clinically relevant improvements in the FACT-An (11.7 points [95 % confidence interval (CI) -4.2 to 27.6]), the Trial Outcome Index-Anemia (10.0 points [95 % CI -4.0 to 24.1]), and fatigue (5.3 points [95 % CI -1.5 to 12.1]). Early-stage BC patients initiating adjuvant chemotherapy have higher than expected rates of sarcopenia and dynapenia which are associated with poorer QoL. RET during adjuvant chemotherapy resulted in the reversal of both sarcopenia and dynapenia; however, only the reversal of sarcopenia was associated with clinically meaningful improvements in QoL.

    We designed new oral formulations containing indomethacin (IMC) solid nanoparticles, and investigate their usefulness by evaluating bioavailability and gastrointestinal lesions. The IMC solid nanoparticles were prepared using methylcellulose (MC), 2-hydroxypropyl-β-cyclodextrin (HPβCD), and the bead mill method, and high quality dispersions containing 1.0% IMC nanoparticles were prepared (IMC(nano), particle size: 76 ± 58 nm, means ± S.D.). The fate of serum IMC and the induction of paw edema in adjuvant-induced arthritis (AA) rats receiving low-doses IMC(nano) (0.4 mg/kg) were similar to those following the administration of a therapeutic dose of conventional IMC prepared with MC and HPβCD (conventional IMC, 2 mg/kg), and the bioavailability in 0.4 mg/kg IMC(nano) was 5.3-fold higher in comparison with that in 2 mg/kg conventional IMC. IMC-induced gastrointestinal lesions in AA rats administered IMC(nano) (8 mg/kg), in consideration of bioavailability, were significantly less than for conventional IMC (40 mg/kg). On the other hand, the toxicity caused by conventional IMC and IMC(nano) was similar in Caco-2 cells. It is possible that the oral administration of IMC solid nanoparticles will show increased effectiveness in treating RA without causing IMC-induced gastrointestinal lesions, since the bioavailability is higher than that of conventional IMC. An oral drug delivery system using drug nanoparticles may expand the usage of NSAIDs for therapy in the inflammatory field.

    Debate continues surrounding the indications for adjuvant and salvage radiotherapy as the published randomized trials have only addressed adjuvant treatment. Salvage radiotherapy has been advocated to limit significant toxicity to patients that would not have benefited from immediate adjuvant radiotherapy. The American Urological Association and American Society for Radiation Oncology guideline released in 2013 has since recommended offering adjuvant therapy to all patients with any adverse features and salvage to those with prostate-specific antigen or local recurrence. The suggested criteria is limited in its application as it potentially subjects patients with few adverse features to adjuvant therapy despite not qualifying as high risk according to established postoperative predictive tools such as the Kattan nomogram. This article reviews the indications for postoperative radiotherapy, limitations of the guideline and alternative prognostication tools for clinicians faced with biochemical or locally recurrent post-prostatectomy prostate cancer.

    TNF-Related Apoptosis-Inducing Ligand (TRAIL) is a well-known apoptosis inducer, which activates the extrinsic death pathway. TRAIL is pro-apoptotic on colon cancer cells, while not cytotoxic towards normal healthy cells. However, its clinical use is limited by cell resistance to cell death which occurs in approximately 50% of cancer cells. Short Chain Fatty Acids (SCFA) are also known to specifically induce apoptosis of cancer cells. In accordance, we have shown that food grade dairy propionibacteria induce intrinsic apoptosis of colon cancer cells, via the production and release of SCFA (propionate and acetate) acting on mitochondria. Here, we investigated possible synergistic effect between Propionibacterium freudenreichii and TRAIL. Indeed, we hypothesized that acting on both extrinsic and intrinsic death pathways may exert a synergistic pro-apoptotic effect. Whole transcriptomic analysis demonstrated that propionibacterial supernatant or propionibacterial metabolites (propionate and acetate), in combination with TRAIL, increased pro-apoptotic gene expression (TRAIL-R2/DR5) and decreased anti-apoptotic gene expression (FLIP, XIAP) in HT29 human colon cancer cells. The revealed synergistic pro-apoptotic effect, depending on both death receptors (TRAIL-R1/DR4, TRAIL-R2/DR5) and caspases (caspase-8, -9 and -3) activation, was lethal on cancer cells but not on normal human intestinal epithelial cells (HIEC), and was inhibited by Bcl-2 expression. Finally, milk fermented by P. freudenreichii induced HT29 cells apoptosis and enhanced TRAIL cytotoxic activity, as did P. freudenreichii DMEM culture supernatants or its SCFA metabolites. These results open new perspectives for food grade P. freudenreichii-containing products in order to potentiate TRAIL-based cancer therapy in colorectal cancer. PMID:26771233

There was no severe toxicity except for grade 3 neutropenia during the first four cycles of TC therapy. However, she developed acute pancreatitis at 14 days after fifth cycle. TC therapy is commonly associated with adverse effects such as myelosuppression, hypersensitivity, alopecia, and peripheral neuropathy, but acute pancreatitis has rarely been reported. Ovarian cancer patients often present with nausea and abdominal pain, which are the same symptoms of pancreatitis. It is very important to keep in mind that acute pancreatitis may be concealed in these common symptoms of ovarian cancer during and after TC therapy. Because acute pancreatitis is fatal complication and quitting the drug usually leads to complete cure. The authors report an uncommon case in which TC therapy may have caused acute pancreatitis.

    We have documented functional and psychosocial changes in patients with extremity soft tissue sarcomas who have undergone multimodality limb-sparing treatments. In 88 patients, parameters related to economic status, sexual activity, pain, limb function, and global quality of life (QOL) were recorded prior to surgery and every 6 months postoperatively. Changes from the preoperative assessment for every parameter were analyzed in each patient. Six months after surgery, there was a decrease in employment status, sexual activity, and in limb function in a significant number of patients. At 12 months, these decreases were still evident. Despite these changes, global QOL measured by a standardized test showed at least some improvement in a significant proportion of patients at 12 months. These findings highlight the difficulty in defining QOL. It could not be ascertained if radiation therapy and/or chemotherapy were causative factors in specific changes because of the small numbers of patients in each subgroup. However, among 60 patients with high-grade sarcomas, significant wound problems developed in 10 of 33 who received postoperative radiation therapy in combination with adjuvant doxorubicin and cyclophosphamide chemotherapy compared with one of 27 patients who received adjuvant chemotherapy alone (P = .016). Also, among high-grade sarcoma patients with 12-month follow-up, six of 19 patients who received radiation therapy and chemotherapy developed joint contractures compared with zero of 15 patients who received chemotherapy alone (P less than .04). The combination of postoperative radiation therapy and chemotherapy appeared to be associated with significantly more tissue-related injury in patients with high-grade sarcomas compared with chemotherapy alone.

    During the last ten years at the National Cancer Institute, 11 patients have received 12 courses of postoperative adjuvant radiation therapy to skin grafts used for wound closure after the resection of soft-tissue sarcomas. The intervals between grafting and the initiation of radiation ranged between 3 and 20 weeks, and 4 patients received chemotherapy at the same time as their radiation. Ten of the 12 irradiated grafts remained intact after the completion of therapy. One graft had several small persistently ulcerated areas that required no further surgical treatment, and one graft required a musculocutaneous flap for reconstruction of a persistent large ulcer. Acute radiation effects on the grafted skin sometimes developed at slightly lower doses than usually seen with normal skin, but these acute effects necessitated a break in therapy on only five occasions. Concurrent chemotherapy and a relatively short interval between grafting and the initiation of radiation seemed to contribute to more severe radiation reactions. This experience indicates that postoperative adjuvant radiation therapy can be delivered to skin grafted areas without undue fear of complications, especially if the graft is allowed to heal adequately prior to initiating therapy and if chemotherapy is not given in conjunction with radiation.

    Abstract Patients with oral cavity squamous cell carcinoma (OSCC) undergoing surgery are recommended to receive adjuvant radiation therapy with or without chemotherapy if there are unfavorable prognostic factors. A positive resection margin (PRM) and extra-capsular extension (ECE) of lymph nodes are well-known major prognostic factors. However, there is no agreement on whether oral cavity cancer patients should receive postoperative chemo-radiotherapy (CCRT) if they present with other risk factors or a combination of 2 or more risk factors. In this study, we investigated this issue and provide suggestions for adjuvant treatments. From January 2002 to December 2013, 567 OSCC patients who had undergone radical surgery were retrospectively reviewed. The 5-year loco-regional control (LRC), distant metastasis-free (DMF), disease-free survival (DFS), and overall survival (OS) were analyzed. In univariate analysis, pathological T classification, positive node, tumor depth, ECE, lymphatic or vascular or perineural invasion and histology grade are significant prognostic factors for LRC, DMF, DFS, or OS. By multivariate analysis, pathological T4 (pT4), positive node, positive surgical margin are prognostic factors for LRC. pT4, positive node and lymphatic invasion predicted for higher rate of distant metastasis. pT4, positive node, and poor differentiation tumor were prognostic factors for DFS. pT4, positive nodes, and ECE were prognostic factors for OS. These factors were used to define risk groups. We proposed PRM and ECE as major risk factors and pT4, positive nodes, close margin (≤ 5 mm, > 1 mm), tumor depth ≥ 1 cm, lymphatic invasion, vascular invasion, perineural invasion, and poor differentiation as minor risk factors. By subgroups analysis, 192 patients with at least 2 minor prognostic factors and no other major risk factors, postoperative radiotherapy (RT), or CCRT yielded significantly better 5-year LRC, DFS, and OS compared to surgery only group.

By subgroups analysis, 192 patients with at least 2 minor prognostic factors and no other major risk factors, postoperative radiotherapy (RT), or CCRT yielded significantly better 5-year LRC, DFS, and OS compared to surgery only group.

    The aim of the present study was to analyze the effect of subtype and body mass index (BMI) on neo-adjuvant chemotherapy (NAC) and postoperative prognosis. Two-hundred and forty nine patients who underwent surgery after NAC were included. A multivariate analysis and survival analysis were used to clarify the relationship between BMI, subtype, and NAC. In the logistic regression model, the pCR rate had a significant relationship with the subtype and tumor stage. In the non-pCR group, more overweight patients had significantly a worse disease-free survival (DFS) compared to normal range patients (Log lank test, p < 0.05). In the Cox proportional hazards model, subtype and tumor stage were significantly associated with decreased DFS. In conclusion, patients with the ER (+), HER (-) type and a high BMI had a high risk for recurrence when they achieved non-pCR after NAC.

    Background Adjuvant chemotherapy for colon cancer has been linked to patient and provider characteristics but little is known about whether distance to chemotherapy providers constitutes an obstacle to chemotherapy. Methods A total of 1,184 Medicaid patients diagnosed with colon cancer in North Carolina in 1999–2002 comprised the sample. Data from the N.C. Central Cancer Registry, N.C. Medicaid Claims, American Hospital Directory and US Census were merged. Logistic regression models were used to estimate the association between chemotherapy receipt and the distance to nearest chemotherapy provider. Results Compared to the referent group of SEER-staged II (local) cancer patients living less than 2 miles from the nearest chemotherapy provider, the odds of receiving chemotherapy fell as the distance to the nearest provider increased. The odds ratio (OR) for those living ≥5 to <15 miles away was 0.13 [95% confidence intervals (CI), 0.04–0.39], and OR for those living ≥15 miles away was 0.06 (95% CI, 0.01–0.52). Patients diagnosed with regional, SEER-staged III (regional) cancer were less likely to receive chemotherapy if they lived in rural areas more than 20 miles away from the nearest provider (OR =0.08; 95% CI, 0.01–0.72). However, we found no evidence of association between chemotherapy receipt and distance to the nearest provider for regional cancer patients living in urban areas and those living in rural areas within 20 miles from the nearest chemotherapy provider. Conclusions Distance to provider may be an obstacle to chemotherapy for some groups of low-income colon cancer patients. Relieving travel burdens of rural patients living far from providers may help Medicaid increase guideline-consistent adjuvant care for regional cancer patients. PMID:27284464

  20. The Efficacy of Ketogenic Diet and Associated Hypoglycemia as an Adjuvant Therapy for High-Grade Gliomas: A Review of the Literature

    Background: A high-fat, low-carbohydrate diet, often referred to as a ketogenic diet (KD), has been suggested to reduce frequency and severity of chronic pediatric and adult seizures. A hypoglycemic state, perpetuated by administration of a KD, has been hypothesized as a potential aid to the current standard treatments of high-grade gliomas. Methods: To understand the effectiveness of the ketogenic diet as a therapy for malignant gliomas, studies analyzing components of a KD were reviewed. Both preclinical and clinical studies were included. The keywords “ketogenic diet, GBM, malignant glioma, hyperglycemia, hypoglycemia” were utilized to search for both abstracts and full articles in English. Overall, 39 articles were found and included in this review. Results: Studies in animal models showed that a KD is able to control tumor growth and increase overall survival. Other pre-clinical studies have suggested that a KD sustains an environment in which tumors respond better to standard treatments, such as chemoradiation. In human cohorts, the KD was well tolerated. Quality of life was improved, compared to a standard, non-calorie or carbohydrate restricted diet. Hyperglycemia was independently associated with diminished survival. Conclusion: Recent clinical findings have demonstrated that induced hypoglycemia and ketogenic diet are tolerable and can potentially be an adjuvant to standard treatments, such as surgery and chemoradiation. Other findings have advocated for KD as a malignant cell growth inhibitor, and indicate that further studies analyzing larger cohorts of GBM patients treated with a KD are needed to determine the breadth of impact a KD can have on GBM treatment.

    Our previous study showed that chromosome region maintenance 1 (CRM1), a nuclear export receptor for various cancer-associated "cargo" proteins, was important in regulating lung carcinogenesis in response to a tobacco carcinogen, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). The objectives of this study are to comprehensively evaluate the significance of CRM1 in lung cancer development and investigate the therapeutic potential of targeting CRM1 for lung cancer treatment using both in vitro and in vivo models. We showed that CRM1 was overexpressed not only in lung tumor tissues from both lung cancer patients and mice treated with NNK but also in NNK-transformed BEAS-2B human bronchial epithelial cells. Furthermore, stable overexpression of CRM1 in BEAS-2B cells by plasmid vector transfection led to malignant cellular transformation. Moreover, a decreased CRM1 expression level in A549 cells by short hairpin siRNA transfection led to a decreased tumorigenic activity both in vitro and in nude mice, suggesting the potential to target CRM1 for lung cancer treatment. Indeed, we showed that the cytotoxic effects of cisplatin on A549 cells with CRM1 down-regulated by short hairpin siRNA were significantly increased, compared with A549 cells, and the cytotoxic effects of cisplatin became further enhanced when the drug was used in combination with leptomycin B, a CRM1 inhibitor, in both in vitro and in vivo models. Cancer target genes were significantly involved in these processes. These data suggest that CRM1 plays an important role in lung carcinogenesis and provides a novel target for lung cancer adjuvant therapy.

    Breast cancer in young women (<40 years) is a rare and complex clinical and psychosocial condition, which deserves multidisciplinary and personalized approaches. In young women with hormone-receptor positive disease, 5 years of adjuvant tamoxifen, with or without ovarian suppression/ablation, is considered the standard endocrine therapy. The definitive role of adjuvant aromatase inhibitors has still to be elucidated: the upcoming results of the Tamoxifen and EXemestane Trial (TEXT) and Suppression of Ovarian Function Trial (SOFT) trials will help understanding if we can widen our current endocrine therapeutic options. The optimal duration of adjuvant endocrine therapy in young women also remains an unresolved issue. The recently reported results of the ATLAS and aTToM trials represent the first evidence of a beneficial effect of extended endocrine therapy in premenopausal women and provide an important opportunity in high-risk young patients. In the metastatic setting, endocrine therapy should be the preferred choice for endocrine responsive disease, unless there is evidence of endocrine resistance or need for rapid disease and/or symptom control. Tamoxifen in combination with ovarian suppression/ablation remains the 1st-line endocrine therapy of choice. Aromatase inhibitors in combination with ovarian suppression/ablation can be considered after progression on tamoxifen and ovarian suppression/ablation. Fulvestrant has not yet been studied in pre-menopausal women. Specific age-related treatment side effects (i.e., menopausal symptoms, change in body image and weight gain, cognitive function impairment, fertility damage/preservation, long-term organ dysfunction, sexuality) and the social impact of diagnosis and treatment (i.e., job discrimination, family management) should be carefully addressed when planning long-lasting endocrine therapies in young women with hormone-receptor positive early and advanced breast cancer.

    Tamoxifen is the most widely used adjuvant endocrine therapy for breast cancer. However, the pharmacogenetic effect of CYP2D6 on its efficacy remains unclear. Therefore, this study aimed to evaluate the association of CYP2D6*10 (c.100C>T) polymorphisms with clinical outcome in Chinese breast cancer patients. A total of 72 tamoxifen-treated early breast cancer patients were included in this study. CYP2D6*10 (c.100C>T) polymorphisms (C/C: wild type; T/T: homozygous mutant genotype T; C/T: heterozygote genotype C) were detected by pyrosequencing. The plasma concentrations of tamoxifen and its two major active metabolites were determined by liquid chromatography tandem mass spectrometry (LC-MS). Disease-free survival (DFS) and overall survival (OS) were assessed by Kaplan-Meier analysis, while the Cox proportional hazards model was used in multivariate tests for prognostic significance. We found that T/T carrier showed the lowest serum concentration of endoxifen as compared to C/C and C/T carriers (p<0.01). In the subgroup of patients below 40 years of age, T/T carriers appeared to have the shortest DFS and OS as compared to other genotype carriers (p<0.01). When genotypes (C/C, C/T and T/T carriers) and other clinical characteristics were adjusted, tumor size (>2 cm) and grades were independent prognostic factors for DFS but not OS (tumor size >2 cm: HR: 3.870, 95% CI: 1.045-14.330, P = 0.043; tumor grades: HR: 2.230, 95% CI: 1.090-4.562, P = 0.028). In conclusion, the T/T genotype is a negative prognostic factor in young breast cancer patients using tamoxifen. Tumor size (>2 cm) and grades are independent prognostic factors for DFS, when genotype of CYP2D6*10 (c.100C>T) is adjusted. PMID:27648149

    With the increasing use of adjuvant chemotherapy for treating early breast cancer, febrile neutropenia management has become crucial. Guidelines for febrile neutropenia management are mostly based on a Caucasian population survey although ethnic differences are reported in terms of adverse events. We survey the current status of febrile neutropenia and risk factors in Japanese female breast cancer patients receiving neoadjuvant and adjuvant chemotherapy regimens potential for febrile neutropenia. Subsequently, we plan to conduct a multicenter prospective cohort study involving 1000 patients with operable breast cancer. With the current state of oral antibiotics being routinely prescribed without hematology tests, we survey febrile neutropenia based on two different definitions, namely, true febrile neutropenia: ≥37.5°C and Grade 4 neutropenia, and surrogate febrile neutropenia: ≥37.5°C and oral antibiotic and antipyretic intake. The comparison of true febrile neutropenia and surrogate febrile neutropenia incidences is anticipated to provide information on the safety and feasibility of chemotherapy management without performing blood tests.

    Purpose The role of postmastectomy radiotherapy in the treatment of T1–2 primary tumor with 1–3 positive lymph nodes is controversial. We compared treatment outcomes between breast conserving surgery followed by radiotherapy (BCS+RT) and total mastectomy alone (TM) in the setting of modern adjuvant systemic treatments. Methods Patients with T1–2 primary breast cancer and 1–3 positive lymph nodes who were treated between 2001 and 2011 were divided into 2 groups based on the treatment approach: BCS+RT (n = 169) and TM (n = 117). All patients received adjuvant chemotherapy including taxanes. Adjuvant endocrine therapy was administered to patients with positive hormone receptors according to their menstrual status. Results During a median follow-up of 76.5 months, 21 patients (7.3%) experienced locoregional recurrence as the first event, including 7 patients (4.1%) in the BCS+RT group and 14 patients (12.0%) in the TM group. The 5-year cumulative incidence rate of locoregional recurrence was 2.5% for BCS+RT versus 9.5% for TM (p = 0.016). Competing risk regression analysis revealed that TM was associated with a relative risk for locoregional recurrence of 5.347 (p = 0.003). TM was also associated with a significantly lower 5-year disease-free survival rate compared with BCS+RT (hazard ratio, 2.024; 95% confidence interval, 1.090–3.759; p = 0.026). Conclusion To improve treatment outcomes for TM even after modern systemic treatments, postmastectomy radiotherapy might be required for patients with T1–2 primary breast cancer and 1–3 positive lymph nodes.

    Introduction: Myxopapillary ependymoma (MPE) is a rare tumor in children. The primary treatment is gross total resection (GTR), with no clearly defined role for adjuvant radiation therapy (RT). Published reports, however, suggest that children with MPE present with a more aggressive disease course. The goal of this study was to assess the role of adjuvant RT in pediatric patients with MPE. Methods: Sixteen patients with MPE seen at Johns Hopkins Hospital (JHH) between November 1984 and December 2010 were retrospectively reviewed. Fifteen of the patients were evaluable with a mean age of 16.8 years (range, 12-21 years). Kaplan-Meier curves and descriptive statistics were used for analysis. Results: All patients received surgery as the initial treatment modality. Surgery consisted of either a GTR or a subtotal resection (STR). The median dose of adjuvant RT was 50.4 Gy (range, 45-54 Gy). All patients receiving RT were treated at the involved site. After a median follow-up of 7.2 years (range, 0.75-26.4 years), all patients were alive with stable disease. Local control at 5 and 10 years was 62.5% and 30%, respectively, for surgery alone versus 100% at both time points for surgery and adjuvant RT. Fifty percent of the patients receiving surgery alone had local failure. All patients receiving STR alone had local failure compared to 33% of patients receiving GTR alone. One patient in the surgery and adjuvant RT group developed a distant site of recurrence 1 year from diagnosis. No late toxicity was reported at last follow-up, and neurologic symptoms either improved or remained stable following surgery with or without RT. Conclusions: Adjuvant RT improved local control compared to surgery alone and should be considered after surgical resection in pediatric patients with MPE.

  9. Patient Education and Adherence to Aerosol Therapy.

    Nonadherence to prescribed medications results in disease instability and poor clinical control, with increases in hospital admissions, emergency room visits, school/work absenteeism, morbidity, and mortality. Poor patient adherence to therapy can be due to lack of cognition, competence, or contrivance. Patients who have not been trained or fail to understand use of drug and device combinations (cognition) often do not have the ability to use an aerosol device correctly (competence). Many patients have the competence to use the device correctly and know why they should use the device in the way they were taught; however, they still contrive to use it in an ineffective and suboptimal manner that reduces its efficiency and effectiveness. Ensuring effective aerosol therapy and optimizing its role in disease management involve not only delivery of aerosolized medications to the lungs, but also understanding why, when, and how to use the medications, competence to use the device, motivation to adhere to therapy, and not contriving to use the device in a way that will prevent effective drug delivery. This paper explains some of the problems with patient education and adherence to aerosol therapy and suggests strategies to evaluate, monitor, and improve patient adherence effectively in primary care. Factors affecting patient adherence to prescribed medications, effective educational interventions, and strategies to promote patient adherence to aerosol therapy are also discussed.

    The results of 144 previously untreated cases of primary Ewing's sarcoma of bone are reported with a minimum follow-up of 5 years. This series was treated between 1972 and 1982 at Istituto Ortopedico Rizzoli with a combined therapy. The local control of the disease consisted of amputation (ten cases), resection followed by radiation therapy (35-45 Gy) (48 cases) and radiation therapy alone (40-60 Gy) (86 cases). Adjuvant chemotherapy, rigorously standardized, was performed according two different protocols: the first (85 cases treated in the period 1972-1978) consisted of vincristine (VCR) Adriamycin (doxorubicin) (ADM), and cyclophosphamide (EDX); the second (59 cases treated in the period 1979-1982) of VCR, ADM, EDX and dactinomycin (DACT). At a follow-up of 5 to 16 years (median, 9), 59 patients (41%) are continuously disease-free (CDF), 81 (56%) developed metastatic disease and/or local recurrence, and four (3%) had a second malignancy. Three factors seem to be correlated to prognosis: the site of the initial lesion (only 23% of the pelvic lesions are represented in the CDF group versus 46% of the other locations); the chemotherapy protocol (32% of the cases in the first protocol are CDF versus 54% in the second); the type of local treatment (60% of the patients treated with amputation or resection plus radiotherapy versus 28% of those treated with radiation therapy alone are CDF). A local recurrence was observed in 24% of the patients (8% in the group locally treated with surgery or surgery plus radiation therapy versus 36% in the group treated with radiation therapy alone). These data suggest that even though adjuvant chemotherapy can improve the long-term results in localized Ewing's sarcoma patients, this disease still represents, in a high percentage of cases, a lethal process whose final prognosis widely depends on the local control of the lesion.

    Purpose: To determine factors predictive of local-regional recurrence (LRR) after surgery alone for carcinomas of the major salivary glands in an attempt to evaluate the potential role of postoperative radiation therapy. Methods and Materials: Between 1960 and 2004, 207 patients with carcinomas of the major salivary glands were treated with definitive surgery without postoperative radiation therapy. Histology was: 67 mucoepidermoid (32%), 50 adenoid cystic (24%), 34 acinic cell (16%), 23 malignant mixed (11%), 16 adenocarcinoma (8%), 6 oncocytic (3%), 6 myoepithelial (3%), and 5 other (2%). Distribution of pathologic T-stage was: 54 T1 (26%), 83 T2 (40%), 46 T3 (22%), and 24 T4 (12%). Sixty patients (29%) had microscopically positive margins. Median follow-up was 6.1 years (range, 0.5-18.7 years). Results: The 5-year and 10-year estimates of local-regional control were 86% and 74%, respectively. A Cox proportional hazard model identified pathologic lymph node metastasis (hazard ratio [HR], 4.8; p = 0.001), high histologic grade (HR, 4.2; p = 0.003), positive margins (HR, 2.6; p = 0.03), and T3-4 disease (HR, 2.0; p = 0.04) as independent predictors of LRR. The presence of any one of these factors was associated with 10-year local-regional control rates of 37% to 63%. Conclusion: Lymph node metastasis, high tumor grade, positive margins, and T3-4 stage predict for significant rates of LRR after surgery for carcinomas of the major salivary glands. Postoperative radiation therapy should be considered for patients with these disease characteristics.

    PS2, an oestrogen-inducible protein, was measured in the cytosol of 230 primary tumours from patients who were subjected to first-line tamoxifen therapy for advanced disease without prior adjuvant therapy with tamoxifen. PS2 correlated positively with oestrogen receptor (ER, P < 0.01) and progesterone receptor content (PgR, P < 0.001), and with the length of progression-free survival (PFS, P = 0.05). Although not statistically significant, higher levels of PS2 (> or = 10 ng mg-1 protein) were also associated with increased probability of response to tamoxifen treatment and a longer total post-relapse survival (PRS). ER, PgR, menopausal status, site of disease and prior adjuvant chemotherapy were all associated with response to tamoxifen therapy and with PFS. In multivariate analysis for PFS, low levels of ER and PgR, visceral metastasis, a disease-free interval of less than 1 year and prior adjuvant chemotherapy were all significantly associated with an increased probability of a rapid disease progression after start of tamoxifen therapy. In the subset of 83 tumours with intermediate levels of ER and PgR (both > or = 10, but not both > or = 75 fmol mg-1 protein), PS2 was positively related with the length of PFS (P < 0.01) and PRS (P < 0.05). PS2 remained the strongest factor in multivariate analysis for PFS (P < 0.01) in this ER/PgR intermediate subgroup, but was not of predictive value in univariate or multivariate analysis for both PFS and PRS in tumours classified as ER/PgR low or high (> or = 75 fmol mg-1 protein). It is concluded that PS2 status may be used as a parameter, additional to ER and PgR, for better refinement of prediction of response to tamoxifen treatment in advanced breast cancer patients especially with intermediate ER/PgR levels in their primary tumour.

    Unwarranted breast cancer adjuvant chemotherapy dose reductions have been documented in black women, women of lower socioeconomic status, and those who are obese. No information on the quality of chemotherapy is available in Hispanic women. The purpose of this study was to characterize factors associated with first cycle chemotherapy dose selection in a multi-ethnic sample of low-income women receiving chemotherapy through the Breast and Cervical Cancer Prevention Treatment Program (BCCPT) and to investigate the impact of Hispanic ethnicity and patient self-efficacy on adjuvant chemotherapy dose selection. Survey and chemotherapy information were obtained from consenting participants enrolled in the California BCCPT. Analyses identified clinical and non-clinical factors associated with first cycle chemotherapy doses less than 90 % of expected doses. Of 552 patients who received chemotherapy, 397 (72 %) were eligible for inclusion. First cycle dose reductions were given to 14 % of the sample. In multivariate analyses, increasing body mass index and non-academic treatment site were associated with doses below 90 % of the expected doses. No other clinical or non-clinical factors, including ethnicity, were associated with first cycle doses selection. In this universally low-income sample, we identified no association between Hispanic ethnicity and other non-clinical patient factors, including patient self-efficacy, in chemotherapy dose selection. As seen in other studies, obesity was associated with systematic dose limits. The guidelines on chemotherapy dose selection in the obese may help address such dose reductions. A greater understanding of the association between type of treatment site and dose selection is warranted. Overall, access to adequate health care allows the vast majority of low-income women with breast cancer to receive high-quality breast cancer chemotherapy. PMID:24596046

No information on the quality of chemotherapy is available in Hispanic women. The purpose of this study was to characterize factors associated with first cycle chemotherapy dose selection in a multi-ethnic sample of low-income women receiving chemotherapy through the Breast and Cervical Cancer Prevention Treatment Program (BCCPT) and to investigate the impact of Hispanic ethnicity and patient self-efficacy on adjuvant chemotherapy dose selection. Survey and chemotherapy information were obtained from consenting participants enrolled in the California BCCPT. Analyses identified clinical and non-clinical factors associated with first cycle chemotherapy doses less than 90 % of expected doses. Of 552 patients who received chemotherapy, 397 (72 %) were eligible for inclusion. First cycle dose reductions were given to 14 % of the sample. In multivariate analyses, increasing body mass index and non-academic treatment site were associated with doses below 90 % of the expected doses. No other clinical or non-clinical factors, including ethnicity, were associated with first cycle doses selection. In this universally low-income sample, we identified no association between Hispanic ethnicity and other non-clinical patient factors, including patient self-efficacy, in chemotherapy dose selection. As seen in other studies, obesity was associated with systematic dose limits. The guidelines on chemotherapy dose selection in the obese may help address such dose reductions. A greater understanding of the association between type of treatment site and dose selection is warranted. Overall, access to adequate health care allows the vast majority of low-income women with breast cancer to receive high-quality breast cancer chemotherapy.

    Purpose This prospective observational study aimed to evaluate the impact of adjuvant chemotherapy on biological and clinical markers of aging and frailty. Methods Women ≥ 70 years old with early breast cancer were enrolled after surgery and assigned to a chemotherapy (Docetaxel and Cyclophosphamide) group (CTG, n=57) or control group (CG, n=52) depending on their planned adjuvant treatment. Full geriatric assessment (GA) and Quality of Life (QoL) were evaluated at inclusion (T0), after 3 months (T1) and at 1 year (T2). Blood samples were collected to measure leukocyte telomere length (LTL), levels of interleukin-6 (IL-6) and other circulating markers potentially informative for aging and frailty: Interleukin-10 (IL-10), Tumor Necrosis Factor Alpha (TNF-α), Insulin-like Growth Factor 1 (IGF-1), Monocyte Chemotactic Protein 1 (MCP-1) and Regulated on Activation, Normal T cell Expressed and Secreted (RANTES). Results LTL decreased significantly but comparably in both groups, whereas IL-6 was unchanged at T2. However, IL-10, TNF-α, IGF-1 and MCP-1 suggested a minor biological aging effect of chemotherapy. Clinical frailty and QoL decreased at T1 in the CTG, but recovered at T2, while remaining stable in the CG. Conclusion Chemotherapy (TC) is unlikely to amplify clinical aging or induce frailty at 1 year. Accordingly, there is no impact on the most established aging biomarkers (LTL, IL-6). PMID:27102154

    Physical illness or disability inevitably has a damaging effect on sexual relationships. Physicians are usually unaware of the sexual consequences of illness on their patients, and lack experience in treating sexual dysfunctions. The report of treatment of a couple with serious cardiovascular disease illustrates the potential efficacy of brief sex therapy for improving the quality of a patient's life. If a primary physician lacks the skills to conduct sex therapy, he may collaborate with nonphysician therapists. The physician's knowledge of the physiological and psychological effects of a specific illness on his patient is essential to successful therapy. Often, simple education, encouragement or reassurance by the physician is enough to overcome the damaging effects of illness on a patient's sex life. PMID:613543

    Purpose Patient perspectives of behavioral voice therapy, including perspectives of treatment adherence, have not been formally documented. Because treatment adherence is to a large extent determined by patient beliefs, assessment of patient perspectives is integral to the study of adherence. Methods Fifteen patients who had undergone at least 2 sessions of direct voice therapy for a variety of voice disorders/complaints were interviewed about their perspectives on voice therapy, with a particular focus on adherence. Interviews were transcribed and analyzed for content according to qualitative methods. Results Three common content themes emerged from the transcripts: Voice Therapy is Hard, Make it Happen, and The Match Matters. Findings are compared to reports of patient experiences in other behavioral interventions such as diet and exercise, and related to existing theoretical models of behavior change and the therapeutic process. Conclusion This study yields information toward the development of scales to measure adherence-related constructs and strategies to improve treatment adherence in voice therapy. PMID:19775866

    Cell replacement therapy is attractive as a novel strategy for stroke patients. To realize this therapy, safer and more effective cell resources are now required. Since both embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) can retain high replication competence and pluripotency when they differentiate into various kinds of cells, they are regarded as a promising cell source for cell replacement therapy. Recent progress includes the combination of novel transcriptional factors that can convert somatic cells to various kinds of mature neuronal cells and neural stem cells without requiring embryonic stem fate. In this paper, we would like to discuss the advantage, issues, and possibility of clinical application of these cells for cell replacement therapy for post-stroke patient. PMID:27333756

    To compare the dosimetric differences between the single-arc volumetric-modulated arc therapy (sVMAT), 3-dimensional conformal radiotherapy (3D-CRT), and intensity-modulated radiotherapy (IMRT) techniques in treatment planning for gastric cancer as adjuvant radiotherapy. Twelve patients were retrospectively analyzed. In each patient's case, the parameters were compared based on the dose-volume histogram (DVH) of the sVMAT, 3D-CRT, and IMRT plans, respectively. Three techniques showed similar target dose coverage. The maximum and mean doses of the target were significantly higher in the sVMAT plans than that in 3D-CRT plans and in the 3D-CRT/IMRT plans, respectively, but these differences were clinically acceptable. The IMRT and sVMAT plans successfully achieved better target dose conformity, reduced the V{sub 20/30}, and mean dose of the left kidney, as well as the V{sub 20/30} of the liver, compared with the 3D-CRT plans. And the sVMAT technique reduced the V{sub 20} of the liver much significantly. Although the maximum dose of the spinal cord were much higher in the IMRT and sVMAT plans, respectively (mean 36.4 vs 39.5 and 40.6 Gy), these data were still under the constraints. Not much difference was found in the analysis of the parameters of the right kidney, intestine, and heart. The IMRT and sVMAT plans achieved similar dose distribution to the target, but superior to the 3D-CRT plans, in adjuvant radiotherapy for gastric cancer. The sVMAT technique improved the dose sparings of the left kidney and liver, compared with the 3D-CRT technique, but showed few dosimetric advantages over the IMRT technique. Studies are warranted to evaluate the clinical benefits of the VMAT treatment for patients with gastric cancer after surgery in the future.

    It is difficult to construct a control group for trials of adjuvant therapy (Rx) of prostate cancer after radical prostatectomy (RP) due to ethical issues and patient acceptance. We utilized 8 curve-fitting models to estimate the time to 60%, 65%, … 95% chance of progression free survival (PFS) based on the data derived from Kattan post-RP nomogram. The 8 models were systematically applied to a training set of 153 post-RP cases without adjuvant Rx to develop 8 subsets of cases (reference case sets) whose observed PFS times were most accurately predicted by each model. To prepare a virtual control group for a single-arm adjuvant Rx trial, we first select the optimal model for the trial cases based on the minimum weighted Euclidean distance between the trial case set and the reference case set in terms of clinical features, and then compare the virtual PFS times calculated by the optimum model with the observed PFSs of the trial cases by the logrank test. The method was validated using an independent dataset of 155 post-RP patients without adjuvant Rx. We then applied the method to patients on a Phase II trial of adjuvant chemo-hormonal Rx post RP, which indicated that the adjuvant Rx is highly effective in prolonging PFS after RP in patients at high risk for prostate cancer recurrence. The method can accurately generate control groups for single-arm, post-RP adjuvant Rx trials for prostate cancer, facilitating development of new therapeutic strategies.

    Background Patient education in early-stage breast cancer has been shown to improve patient well-being and quality of life, but it poses a challenge given the increasingly complex regimens and time constraints in clinical practice. Technology-aided teaching in the clinic could help to improve the understanding of adjuvant systemic therapy for patients. In this prospective pilot study, we used a clinician-administered, tablet-based teaching aid to teach patients with early-stage breast cancer about adjuvant systemic therapy. Methods Participation was offered to newly diagnosed patients with early-stage breast cancer presenting for their first medical oncology visit at a provincial cancer centre. Participants were shown a tablet-based presentation describing procedures, rationales, risks, and benefits of adjuvant systemic therapy as an adjunct to a discussion with the medical oncologist. After the clinic visit, participants completed a questionnaire measuring satisfaction with the visit and knowledge of the treatment plan discussed. Results The 25 patients recruited for the study had a mean age of 57 years. An offer of upfront chemotherapy alone was made to 12 participants (48%), chemotherapy with trastuzumab to 4 (16%), and hormonal therapy to 9 (36%). Correct answers to all questions related to treatment knowledge were given by 22 patients (88%). Satisfaction with the clinic visit was high (mean satisfaction score: 4.53 ± 0.1 of a possible 5). Conclusions We found that a tablet-based presentation about adjuvant systemic therapy was satisfactory to patients with early-stage breast cancer and that knowledge retention after the clinic visit was high. Tablet-based teaching could be a feasible and effective way of educating patients in the breast oncology clinic and warrants further investigation in randomized studies. PMID:26628877

    Purpose Neurotoxicity from adjuvant treatment with oxaliplatin has been studied in colorectal patients in short-term studies, but this is the first long-term assessment from the National Surgical Adjuvant Breast and Bowel Project (NSABP) investigating whether excess neurotoxicity persists beyond 4 years. Patients and Methods As part of a colorectal cancer long-term survivor study (LTS-01), long-term neurotoxicity was assessed in 353 C-07 patients (cross-sectional sample). Ninety-two of these LTS-01 patients also had longitudinal data and were re-assessed at 5-8 (median 7) years from randomization (longitudinal sample). Contingency tables compared cohorts, a mixed model compared neurotoxicity between treatments over time, and a Wilcoxon rank sum test compared neurotoxicity between treatments (cross-sectional sample). Results In the cross-sectional sample, the increase in mean total neurotoxicity scores of 1.8 with oxaliplatin was statistically significant (P= .005), but not clinically significant (minimally important difference was 4 at the long-term assessment. Patients treated with oxaliplatin had increased odds of numbness and tingling in hands (OR= 2.00, P= .015) and feet (OR= 2.78, P< .001) versus patients treated without oxaliplatin. The magnitude of the oxaliplatin effect varied with time (P< .001) in the longitudinal sample such that oxaliplatin-treated patients did not have significantly greater total neurotoxicity scores by 7 years. Conclusion At the long-term endpoint, there was no clinically significant increase in total neurotoxicity scores for patients treated with oxaliplatin, but the specific neurotoxicities of numbness and tingling of the hands and feet remained significantly elevated for oxaliplatin-treated patients.

    Adjuvant chemotherapy (ACT) after radical surgery is known to improve the survival of patients with non-small cell lung cancer (NSCLC). However, there are few studies reporting the impact of age on the efficacy of ACT in NSCLC patients. All patients who received postoperative ACT in the Cancer Hospital, the Chinese Academy of Medical Sciences, between 2001 and 2013 with complete records in the database of the hospital and met the inclusion criteria were enrolled in this study for analysis. The primary end point was disease-free survival (DFS) in terms of age. Survival analysis was performed using Kaplan-Meier estimates, log-rank tests, and Cox's proportional hazards regression analysis. Propensity score matching (PSM) was used, survival analysis and subgroup analysis of the match data were carried out. Of 1095 patients with stage IB to stage IIIA NSCLC who underwent radical resection, 865 cases who met the inclusion criteria were analyzed. Of them, 156 (18.0%) patients were 65 years old or older, and the remaining 709 (82.0%) patients were younger than 65. The DFS between the younger group and the elderly group was not significantly different neither before PSM (100.714 weeks [95% CI: 84.421, 117.007] vs. 99.571 weeks [95% CI: 82.621, 116.522]; P = 0.555) nor after PSM (104.857 weeks [95% CI: 81.495, 128.220] vs. 97.429 weeks [95% CI: 81.743, 113.114]; P = 0.328) using the Kaplan-Meier method.The results suggest that the benefit on DFS was similar regardless of age of NSCLC patients. ACT should not be withheld from elderly patients. However, these conclusions are limited by the nature of this retrospective study, and therefore prospective trials are required for further verification. PMID:27367482

    An increasing body of literature indicates that chemotherapy (ChT) for breast cancer (BC) is associated with adverse effects on the brain. Recent research suggests that cognitive and brain function in patients with BC may already be compromised before the start of chemotherapy. This is the first study combining neuropsychological testing, patient-reported outcomes, and multimodal magnetic resonance imaging (MRI) to examine pretreatment cognition and various aspects of brain function and structure in a large sample. Thirty-two patients with BC scheduled to receive ChT (pre-ChT+), 33 patients with BC not indicated to undergo ChT (pre-ChT−), and 38 no-cancer controls (NCs) were included. The examination consisted of a neuropsychological test battery, self-reported aspects of psychosocial functioning, and multimodal MRI. Patients with BC reported worse scores on several aspects of quality of life, such as higher levels of fatigue and stress. However, cortisol levels were not elevated in the patient groups compared to the control group. Overall cognitive performance was lower in the pre-ChT+ and the pre-ChT− groups compared to NC. Further, patients demonstrated prefrontal hyperactivation with increasing task difficulty on a planning task compared to NC, but not during a memory task. White matter integrity was lower in both patient groups. No differences in regional brain volume and brain metabolites were found. The cognitive and imaging data converged to show that symptoms of fatigue were associated with the observed abnormalities; the observed differences were no longer significant when fatigue was accounted for. This study suggests that cancer-related psychological or biological processes may adversely impact cognitive functioning and associated aspects of brain structure and function before the start of adjuvant treatment. Our findings stress the importance to further explore the processes underlying the expression of fatigue and to study whether it has a

    Acupuncture is one of the most important parts of Traditional Chinese Medicine, has been used for more than 3000 years as prevention and treatment for various diseases in China as well as in adjacent regions, and is widely accepted in western countries in recent years. More and more clinical trials revealed that acupuncture shows positive effect in stroke, not only as a complementary and alternative medicine for poststroke rehabilitation but also as a preventive strategy which could induce cerebral ischemic tolerance, especially when combined with modern electrotherapy. Acupuncture has some unique characteristics, which include acupoint specificity and parameter-dependent effect. It also involves complicated mechanism to exert the beneficial effect on stroke. Series of clinical trials have shown that acupuncture primarily regulates the release of neurochemicals, hemorheology, cerebral microcirculation, metabolism, neuronal activity, and the function of specific brain region. Animal studies showed that the effects of acupuncture therapy on stroke were possibly via inhibition of postischemic inflammatory reaction, stimulation of neurogenesis and angiogenesis, and influence on neural plasticity. Mechanisms for its preconditioning effect include activity enhancement of antioxidant, regulation of the endocannabinoid system, and inhibition of apoptosis. Although being controversial, acupuncture is a promising preventive and treatment strategy for stroke, but further high-quality clinical trials would be needed to provide more confirmative evidence.

  6. Outcome of patients with HER2-positive breast cancer treated with or without adjuvant trastuzumab in the Finland Capecitabine Trial (FinXX)

    2014-01-01

    Background. Little information is available about survival outcomes of patients with HER2-positive early breast cancer treated with adjuvant capecitabine-containing chemotherapy with or without trastuzumab. Patients and methods. One thousand and five hundred patients with early breast cancer were entered to the Finland Capecitabine trial (FinXX) between January 2004 and May 2007, and were randomly assigned to receive either three cycles of adjuvant TX (docetaxel, capecitabine) followed by three cycles of CEX (cyclophosphamide, epirubicin, capecitabine; TX-CEX) or three cycles of docetaxel followed by three cycles of CEF (cyclophosphamide, epirubicin, fluorouracil; T-CEF). The primary endpoint was recurrence-free survival (RFS). The study protocol was amended in May 2005 while study accrual was ongoing to allow adjuvant trastuzumab for patients with HER2-positive cancer. Of the 284 patients with HER2-positive cancer accrued to FinXX, 176 (62.0%) received trastuzumab after amending the study protocol, 131 for 12 months and 45 for nine weeks. The median follow-up time was 6.7 years. Results. Patients with HER2-positive cancer who received trastuzumab had better RFS than those who did not (five-year RFS 89.2% vs. 75.9%; HR 0.41, 95% CI 0.23–0.72; p = 0.001). Patients treated with trastuzumab for 12 months or nine weeks had similar RFS. There was no significant interaction between trastuzumab administration and the type of chemotherapy. Four (2.3%) patients treated with trastuzumab had heart failure or left ventricular dysfunction, three of these received capecitabine. Conclusion. Adjuvant trastuzumab improves RFS of patients treated with TX-CEX or T-CEF. Few patients had cardiac failure. PMID:23957715

    There are relatively few case reports of electroconvulsive therapy (ECT) in patients with multiple sclerosis. We present 3 such patients, all of whom received safe, effective ECT without evidence of acute neurological deterioration. We conclude that patients with multiple sclerosis being considered for ECT should have a thorough neurological evaluation, and the informed consent process should include discussion of the possibility of neurological deterioration. However, review of the literature and of our 3 cases does reveal that ECT can be used safely, at least in the short term. Long-term outcomes in such patients remain uncertain.

    Interleukin-1 receptor antagonist (IL-1Ra), is a natural blocker of the inflammatory cytokine interleukin-1. Using a rat adjuvant-induced arthritis (AIA) model of rheumatoid arthritis (RA), we examined the protective effects of IL-1Ra in bone metabolism in vivo after folate-mediated nonviral gene delivery. We detected secreted human IL-1Ra protein in serum and cultured primary osteoblasts of rats that were treated with chitosan-IL-1Ra and folate-IL-1Ra-chitosan nanoparticles, respectively. In vivo, IL-1Ra gene delivery significantly reverted alterations in bone turnover observed in arthritic animals by modulating the level of osteocalcin (OC) as well as the activities of alkaline phosphatase and tartrate-resistant acid phosphatase. The protective effects of these nanoparticles were evident from the decrease in the expression levels of interleukine-1beta and prostaglandin E(2) as well as osteoclast number and other histopathological findings. Compared to naked DNA and chitosan-DNA, folate-chitosan-DNA nanoparticles were less cytotoxic and enhanced IL-1Ra protein synthesis in vitro and offered a better protection against inflammation and abnormal bone metabolism in vivo. Nonviral gene therapy with folate-chitosan-DNA nanoparticles containing the IL-1 Ra gene seemed to protect against bone damage and inflammation in rat adjuvant-induced arthritis model.

    High incidence of intrahepatic recurrence is a major surgical limitation following hepatectomy of hepatocellular carcinoma (HCC). This study was intended to investigate the effects of adjuvant intrahepatic injection of iodine-131-lipiodol on disease recurrence and survival in patients with HCC who underwent resection. A computerized literature search was performed to identify relevant articles. Data synthesis was performed using Review Manager 5.0 software, and results are presented as odds ratio (OR) with 95 % confidence intervals. Two randomized controlled trials and three case-control studies with a total of 334 participants were analyzed. Iodine-131-lipiodol treatment achieved significantly lower rates of intrahepatic recurrence (OR = 0.48, 95 % confidence interval (95 % CI) = 0.30-0.74; P = 0.001) and early recurrence (<2 year) (OR = 0.45, 95 % CI = 0.23-0.89; P = 0.02). Likewise, iodine-131-lipiodol treatment improved both the 5-year disease-free survival and overall survival significantly (OR = 1.85, 95 % CI = 1.13-3.03; P = 0.01; OR = 2.00, 95 % CI = 0.99-4.04; P = 0.05, respectively). Adjuvant intrahepatic injection of iodine-131-lipiodol resulted in a preventive effect on recurrence and improved survival after resection of HCC. Further larger, multi-centred, randomized prospective trial is warranted. PMID:27011542

    The evolution of inflammatory diseases has radically changed since the introduction of biologic therapies, such as tumour necrosis factor alpha inhibitors (anti-TNFα). They, therefore, represent a widely used therapeutic modality. Nevertheless, post-marketing studies reveal an increased risk of infection in patients taking these drugs, especially granulomatous infections such as listeriosis. We aimed to evaluate the reported cases of listeriosis in patients treated with biologic treatments. We used the United States Food and Drug Administration (FDA) Adverse Event Reporting System (AERS) from 2004 to 2011. We also perform a literature review of previously reported cases of listeriosis in patients taking biologic therapies. We identified 266 cases of Listeria monocytogenes infection associated with biologic therapies. The majority of patients were receiving infliximab (77.1 %), followed by etanercept (11.7 %), adalimumab (9.8 %), rituximab (4.1 %), abatacept (0.4 %) and golimumab (0.4 %). Indications for the use of biologics were as follows: 47.7 % for rheumatologic diseases, 38 % for inflammatory bowel diseases, 3.4 % for haematological diseases and 10.5 % for other indications. Seventy-three percent of the patients were receiving concomitant immunosuppressant drugs, especially steroids (56 %) and methotrexate (31.6 %). The median time to the onset of infection was 184 days. Mortality rates range from 11.1 % in adalimumab-treated patients to 27.3 % in rituximab-treated patients (p = 0.7). Listeriosis is common in biologics-treated patients, especially related to infliximab use given concomitantly with other immunosuppressive therapies. Infections after treatment with biologics mostly occurred in the first year after initiating treatment. PMID:23568606

    Vaccines and autoimmunity are linked fields. Vaccine efficacy is based on whether host immune response against an antigen can elicit a memory T-cell response over time. Although the described side effects thus far have been mostly transient and acute, vaccines are able to elicit the immune system towards an autoimmune reaction. The diagnosis of a definite autoimmune disease and the occurrence of fatal outcome post-vaccination have been less frequently reported. Since vaccines are given to previously healthy hosts, who may have never developed the disease had they not been immunized, adverse events should be carefully accessed and evaluated even if they represent a limited number of occurrences. In this review of the literature, there is evidence of vaccine-induced autoimmunity and adjuvant-induced autoimmunity in both experimental models as well as human patients. Adjuvants and infectious agents may exert their immune-enhancing effects through various functional activities, encompassed by the adjuvant effect. These mechanisms are shared by different conditions triggered by adjuvants leading to the autoimmune/inflammatory syndrome induced by adjuvants (ASIA syndrome). In conclusion, there are several case reports of autoimmune diseases following vaccines, however, due to the limited number of cases, the different classifications of symptoms and the long latency period of the diseases, every attempt for an epidemiological study has so far failed to deliver a connection. Despite this, efforts to unveil the connection between the triggering of the immune system by adjuvants and the development of autoimmune conditions should be undertaken. Vaccinomics is a field that may bring to light novel customized, personalized treatment approaches in the future.

    This review focuses on the role of interleukin (IL)-12, a proinflammatory cytokine with pleiotropic effects as a potent immunoregulatory molecule and hematopoietic growth factor, in infection with Plasmodium parasites, the causative agents of malaria. IL-12 has been demonstrated to have profound effects on the immune response to blood-stage malaria, to induce protection, and to alleviate malarial anemia. In combination with an anti-malarial drug, IL-12 is effective in an established malaria infection. This cytokine also has potent immune effects as a malaria vaccine adjuvant. However, IL-12 can also mediate pathology during blood-stage malaria.

    ABSTRACT Purpose: To determine the effectiveness of adjuvant dendritic cell (DC) vaccination to induce tumor-specific immunological responses in stage III melanoma patients. Experimental design: Retrospective analysis of stage III melanoma patients, vaccinated with autologous monocyte-derived DC loaded with tumor-associated antigens (TAA) gp100 and tyrosinase after radical lymph node dissection. Skin-test infiltrating lymphocytes (SKILs) obtained from delayed-type hypersensitivity skin-test biopsies were analyzed for the presence of TAA-specific CD8+ T cells by tetrameric MHC-peptide complexes and by functional TAA-specific T cell assays, defined by peptide-recognition (T2 cells) and/or tumor-recognition (BLM and/or MEL624) with specific production of Th1 cytokines and no Th2 cytokines. Results: Ninety-seven patients were analyzed: 21 with stage IIIA, 34 with stage IIIB, and 42 had stage IIIC disease. Tetramer-positive CD8+ T cells were present in 68 patients (70%), and 24 of them showed a response against all 3 epitopes tested (gp100:154–162, gp100:280–288, and tyrosinase:369–377) at any point during vaccinations. A functional T cell response was found in 62 patients (64%). Rates of peptide-recognition of gp100:154–162, gp100:280–288, and tyrosinase:369–377 were 40%, 29%, and 45%, respectively. Median recurrence-free survival and distant metastasis-free survival of the whole study population were 23.0 mo and 36.8 mo, respectively. Conclusions: DC vaccination induces a functional TAA-specific T cell response in the majority of stage III melanoma patients, indicating it is more effective in stage III than in stage IV melanoma patients. Furthermore, performing multiple cycles of vaccinations enhances the chance of a broader immune response. PMID:27622047

    Over recent years, adjuvant systemic treatment guidelines (AST) for early-stage breast cancer have changed considerably. We aimed to assess the impact of these guideline changes on the administration of AST in early-stage breast cancer patients and to what extent these guidelines are adhered to at a nation-wide level. We used Netherlands Cancer Registry data to describe trends in AST prescription, adherence to AST guidelines, and to identify clinicopathological determinants of nonadherence. Between 1990 and 2012, 231,648 Dutch patients were diagnosed with early breast cancer, of whom 124,472 received AST. Adjuvant endocrine treatment (ET) use increased from 23 % of patients (1990) to 56 % (2012), and chemotherapy from 11 to 44 %. In 2009-2012, 8 % of patients received ET and 3 % received chemotherapy without guideline indication. Conversely, 10-29 % of patients did not receive ET and chemotherapy, respectively, despite a guideline indication. Unfavorable clinicopathological characteristics generally decreased the chance of undertreatment and increased the chance for overtreatment. Remarkable was the increased chance of ET undertreatment in younger women (RR < 35 vs 60-69 years 1.79; 95 % CI 1.30-2.47) and in women with HER2+ disease (RR 1.64; 95 % CI 1.46-1.85). Over the years, AST guidelines expanded resulting in much more Dutch early breast cancer patients receiving AST. In the majority of cases, AST administration was guideline concordant, but the high frequency of chemotherapy undertreatment in some subgroups suggests limited AST guideline support in these patients.

    Introduction Visible hematuria is not rare in patients on anticoagulant therapy. There is no consensus regarding the diagnostic approach for them; some authors suggest restricted volume of diagnostic procedures because of the low number of urological etiology found. Some antibiotics have been reported to potentiate the effect of oral anticoagulants. Material and methods The study addresses the need for urological assessment of patients on anticoagulation therapy and the possible role of some drugs administrated simultaneously with an oral anticoagulant, for the onset of macroscopic hematuria. Patients hospitalized with hematuria, both with or without anticoagulation therapy, were investigated and followed up. Results The onset of hematuria depends on the monitoring of oral anticoagulation. INR (International Normalized Ratio) value corresponds with the probability of non-urological etiology, where INR>4 carries relatively low risk for urological and malignant etiology. Some antibiotics may influence the anticoagulation effect, so INR value may be elevated and hematuria may occur. Conclusions Anticoagulation therapy should be administrated carefully and individually. The risk of urological etiology of hematuria is lower in patients on oral anticoagulants (especially when INR >4), however, it is not zero. PMID:26568876

    Purpose: A prospective randomized trial was performed to evaluate the efficacy of concurrent chemotherapy and adjuvant chemotherapy in patients with locoregionally advanced nasopharyngeal carcinoma (NPC) in endemic regions of China. Methods and Materials: Between July 2002 and September 2005, 316 eligible patients were randomly assigned to receive either radiotherapy alone (RT) or chemoradiotherapy concurrent with adjuvant chemotherapy (CRT). All patients received 70 Gy in 7 weeks using standard RT portals and techniques. The CRT patients were given concurrent cisplatin (40 mg/m{sup 2} on Day 1) weekly during RT, followed by cisplatin (80 mg/m{sup 2} on Day 1) and fluorouracil (800 mg/m{sup 2} on Days 1-5) every 4 weeks (Weeks 5, 9, and 13) for three cycles after completion of RT. All patients were analyzed by intent-to-treat analysis. Results: The two groups were well-balanced in all prognostic factors and RT parameters. The CRT group experienced significantly more acute toxicity (62.6% vs. 32%, p = 0.000). A total of 107 patients (68%) and 97 patients (61%) completed all cycles of concurrent chemotherapy and adjuvant chemotherapy, with a median follow-up time of 29 months. The 2-year overall survival rate, failure-free survival rate, distant failure-free survival rate, and locoregional failure-free survival rate for the CRT and RT groups were 89.8% vs. 79.7% (p = 0.003), 84.6% vs. 72.5% (p = 0.001), 86.5% vs. 78.7% (p = 0.024), and 98.0% vs. 91.9% (p = 0.007), respectively. Conclusions: This trial demonstrated the significant survival benefits of concurrent chemotherapy plus adjuvant chemotherapy in patients with locoregionally advanced NPC in endemic regions of China.

    Background Neoplasms of histiocytic and dendritic cell origin, including follicular dendritic cell sarcoma (FDCS), histiocytic sarcoma (HS) and interdigitating dendritic cell sarcoma (IDCS), are extremely rare, and data on their natural history and treatment outcomes are sparse. We evaluated the impact of surgery, radiation and systemic therapies on overall survival (OS). Methods We conducted a retrospective chart review of patients with FDCS, IDCS and HS treated at Memorial Sloan Kettering Cancer Center between 1995 and 2014. Results We identified 31, 15 and 7 patients with FDCS, HS and IDCS, respectively. Median age was 48.7, 42.3 and 58.8 years for FDCS, HS and IDCS, respectively. Only a slight disparity in gender distribution existed for FDCS and HS; however, IDCS predominantly affected males (6:1). The most common sites of presentation were abdomen and pelvis (42%), extremities (33%) and head and neck (57%) for FDCS, HS and IDCS, respectively. At diagnosis, 74%, 40% and 86% of patients presented with localised disease in FDCS, HS and IDCS, respectively. Patients with localised disease had significantly improved OS than those with metastatic disease in FDCS (P = 0.04) and IDCS (P = 0.014) but not in HS (P = 0.95). In FDCS and HS, adjuvant or neo-adjuvant therapy was not associated with improved OS compared with observation. In IDCS, surgery alone provided a 5-year overall survival rate of 71%. Conclusions Adjuvant or neo-adjuvant treatment in FDCS and HS did not affect OS. Patients with IDCS had an excellent outcome with surgery. In the metastatic setting, chemotherapy and small molecule inhibitors may provide benefit. PMID:26298731

    Purpose Retrospective studies suggest that primary breast cancers lacking estrogen receptor (ER) and progesterone receptor (PR) and not overexpressing human epidermal growth factor receptor 2 (HER2; triple-negative tumors) are particularly sensitive to DNA-damaging chemotherapy with alkylating agents. Patients and Methods Patients enrolled in International Breast Cancer Study Group Trials VIII and IX with node-negative, operable breast cancer and centrally assessed ER, PR, and HER2 were included (n = 2,257). The trials compared three or six courses of adjuvant classical cyclophosphamide, methotrexate, and fluorouracil (CMF) with or without endocrine therapy versus endocrine therapy alone. We explored patterns of recurrence by treatment according to three immunohistochemically defined tumor subtypes: triple negative, HER2 positive and endocrine receptor absent, and endocrine receptor present. Results Patients with triple-negative tumors (303 patients; 13%) were significantly more likely to have tumors > 2 cm and grade 3 compared with those in the HER2-positive, endocrine receptor–absent, and endocrine receptor–present subtypes. No clear chemotherapy benefit was observed in endocrine receptor–present disease (hazard ratio [HR], 0.90; 95% CI, 0.74 to 1.11). A statistically significantly greater benefit for chemotherapy versus no chemotherapy was observed in triple-negative breast cancer (HR, 0.46; 95% CI, 0.29 to 0.73; interaction P = .009 v endocrine receptor–present disease). The magnitude of the chemotherapy effect was lower in HER2-positive endocrine receptor–absent disease (HR, 0.58; 95% CI, 0.29 to 1.17; interaction P = .24 v endocrine receptor–present disease). Conclusion The magnitude of benefit of CMF chemotherapy is largest in patients with triple-negative, node-negative breast cancer. PMID:20458051

    Oral health care in patients undergoing chemotherapy and/or radiation therapy can be complex. Care delivered by a multidisciplinary approach is timely and streamlines the allocation of resources to provide prompt care and to attain favorable outcomes. A hospital dentist, oral and maxillofacial surgeon, and a maxillofacial prosthodontist must be involved early to prevent avoidable oral complications. Prevention and thorough preparation are vital before the start of chemotherapy and radiation therapy. Oral complications must be addressed immediately and, even with the best management, can cause delays and interruption in treatment, with serious consequences for the outcome and prognosis.

    Purpose: Adjuvant radiotherapy (RT) is frequently recommended for node-positive head and neck squamous cell carcinoma (HNSCC) treated with primary surgery. The impact of RT on survival for various subgroups of node-positive HNSCC has not been clearly demonstrated. Methods and Materials: Within the Surveillance, Epidemiology, and End Results (SEER) Database, we identified 5297 patients with node-positive (N1 to N3) HNSCC treated with definitive surgery with or without adjuvant RT between 1988 and 2001. The median follow-up was 4.4 years. Results: Adjuvant RT significantly improved 5-year overall survival (46.3%: 95% confidence interval [CI], 44.7-48.0% for surgery + RT, vs. 35.2%: 95% CI, 32.0-38.5% for surgery alone, p < 0.001) and cancer-specific survival (54.8%: 95% CI, 53.2-56.4% for surgery + RT, vs. 46.2% for surgery alone 95% CI, 42.4-50.0%, p < 0.05). Use of adjuvant RT remained a significant predictor of survival on multivariable analysis (hazard ratio [HR], 0.75; 95% CI, 0.68-0.83; p < 0.001). Subset analyses demonstrated that adjuvant RT was associated with significantly improved survival for N1 (HR, 0.78; 95% CI; 0.67-0.90; p = 0.001), N2a (HR, 0.82; 95% CI, 0.67-0.99, p = 0.048) and N2b to N3 nodal disease (HR, 0.62; 95% CI, 0.51-0.75; p < 0.001). Adjuvant RT increased overall survival for node-positive patients with oropharynx (HR, 0.72; 95% CI, 0.57-0.90; p 0.004), hypopharynx (HR, 0.66; 95% CI, 0.49 to 0.88; p = 0.004), larynx (HR, 0.66; 95% CI, 0.52-0.84; p = 0.001), and oral cavity (HR, 0.84; 95% CI, 0.73-0.98; p = 0.025) primary tumors. Conclusions: In a large population-based analysis, adjuvant RT significantly improves overall survival for patients with node-positive HNSCC. All nodal stages, including N1, appear to benefit from the addition of RT to definitive surgery.

    Performance and clinical characteristics of a novel hyperthermia antenna operating at 434 MHz were evaluated for the adjuvant treatment of locally advanced superficial tumours in cats, dogs and horses. Electromagnetic simulations were performed to determine electric field characteristics and compared to simulations for a flat microwave antenna with similar dimensions. Simulation results show a reduced skin surface and backfield irradiation and improved directional irradiation (at broadside) compared to a flat antenna. Radiated power and penetration is notably increased with a penetration depth of 4.59 cm compared to 2.74 cm for the flat antenna. Clinical use of the antenna was then evaluated in six animals with locoregionally advanced solid tumours receiving adjuvant chemotherapy. During clinical applications, therapeutic temperatures were achieved at depths ≥4 cm. Objective responses were seen in all patients; tissue toxicity in one case limited further therapy. This antenna provides compact, efficient, focused and deep-penetrating clinical hyperthermia for the treatment of solid tumours in veterinary patients.

    The treatment of endometrial cancer begins with surgery, including total abdominal hysterectomy, bilateral salpingo-oophorectomy, peritoneal lavage, and a consideration for lymph node evaluation. Selection of adjuvant therapy is based on an approximation of the risk of recurrence with features such as stage, tumor histology, lymphovascular space invasion, and patient age. The role of adjuvant radiation therapy in patients with intermediate risk of recurrence is a matter of ongoing controversy. Several randomized trials indicate that adjuvant radiation therapy improves loco-regional control. However, the ideal form of radiation therapy in these patients continues to be under debate.

    Epilepsy is one of the major neurological disorders still awaiting safer drugs with improved antiepileptic effect and lesser side effects. Apart from epilepsy itself, AEDs also have been shown to induce cognitive impairment in patients with epilepsy. There are limited data for the treatment of this menace. As cholinergic approach has widely been practiced for the restoration of memory in various neurodegenerative disorders, this study was envisaged to evaluate add on effect of acetylcholinesterase inhibitor (tacrine) with phenytoin in pentylenetetrazole-kindling-induced learning and memory deficit in mice. In this study, mice were kindled using subconvulsive dose of pentylenetetrazole (35 mg/kg, i.p.; at interval of 48 ± 2 hr) and successfully kindled animals were divided into different groups and treated with vehicle, phenytoin and phenytoinin in combination with tacrine (0.3 mg/kg), atropine (1 mg/kg) and tacrine + atropine. Effect of different interventions on learning and memory was evaluated using elevated plus maze and passive shock avoidance on days 5, 10, 15 and 20. Phenytoin-treated kindled animals were associated with learning and memory deficit, while tacrine supplementation improved memory deficit with increased seizure severity score. Atropine treatment significantly reversed the protective effect of tacrine. Neurochemical findings also support the behavioural finding of the study. Our results suggest the use of anticholinesterases, with better seizure tolerance, for the management of cognitive impairment of epilepsy, as adjunct therapy.

    Background This study aims to compare the efficacy and safety between zoledronic acid combined with calcium and calcium alone to prevent aromatase inhibitor-associated bone loss for postmenopausal breast cancer patients receiving adjuvant letrozole. Methods One hundred twenty patients were randomly divided into two groups, A and B. Patients in group A (n=60) received modified radical mastectomy or breast-conserving surgery + four cycles of AC followed by T regimen (optional) + radiotherapy (optional) + letrozole 2.5 mg daily + calcium 500 mg twice daily + vitamin D 400 international units daily +4 mg of zoledronic acid every 6 months, while patients in group B (n=60) were not given zoledronic acid and the rest of the treatments of group B were the same as group A. All the patients were followed up for 1 year. The primary endpoint was the intrapatient percentage change in lumbar spine (LS) bone mineral density (BMD) from baseline to month 12. Secondary endpoints included the percentage change in total hip (TH) and femoral neck (FN) BMD, the incidence of osteoporosis, the incidence of a clinically meaningful 5% decline in BMD at 1 year, change of serum N-telopeptide of type 1 collagen (NTX) and bone-specific alkaline phosphatase (BSAP) concentrations. Results Patients in group A had a statistically significant higher average change and average percent change in LS, FN, and TH than group B. Group A had a statistically significant lower incidence of a clinically meaningful loss of bone density at the LS, FN, or TH than Group B. The incidence of osteoporosis in group A was significantly lower than group B. The decreases in NTX and BSAP concentrations from baseline to month 12 in patients of group A were significant; in contrast, patients in group B were found to have increases in NTX and BSAP concentrations from baseline. The most common adverse reactions in patients are flu-like symptoms (38%), bone pain (28%), and joint pain (20%). Conclusion AI-associated bone loss

    Purpose This study aims to compare the dosimetric data of local tumor's bed dose escalation (boost) with photon beams (external beam radiation therapy – EBRT) versus high-dose-rate interstitial brachytherapy (HDR-BT) after breast-conserving treatment in women with early-stage breast cancer. Material and methods We analyzed the treatment planning data of 136 irradiated patients, treated between 2006 and 2013, who underwent breast-conserving surgery and adjuvant whole breast irradiation (WBI; 50.4 Gy) and boost (HDR-BT: 10 Gy in one fraction [n = 36]; EBRT: 10 Gy in five fractions [n = 100]). Organs at risk (OAR; heart, ipsilateral lung, skin, most exposed rib segment) were delineated. Dosimetric parameters were calculated with the aid of dose-volume histograms (DVH). A non-parametric test was performed to compare the two different boost forms. Results There was no difference for left-sided cancers regarding the maximum dose to the heart (HDR-BT 29.8% vs. EBRT 29.95%, p = 0.34). The maximum doses to the other OAR were significantly lower for HDR-BT (Dmax lung 47.12% vs. 87.7%, p < 0.01; rib 61.17% vs. 98.5%, p < 0.01; skin 57.1% vs. 94.75%, p < 0.01; in the case of right-sided breast irradiation, dose of the heart 6.00% vs. 16.75%, p < 0.01). Conclusions Compared to EBRT, local dose escalation with HDR-BT presented a significant dose reduction to the investigated OAR. Only left-sided irradiation showed no difference regarding the maximum dose to the heart. Reducing irradiation exposure to OAR could result in a reduction of long-term side effects. Therefore, from a dosimetric point of view, an interstitial boost complementary to WBI via EBRT seems to be more advantageous in the adjuvant radiotherapy of breast cancer.

    Background Aromatase inhibitors provide superior disease control when compared with tamoxifen as adjuvant therapy for postmenopausal women with endocrine-responsive early breast cancer. Purpose To present the design, history, and analytic challenges of the Breast International Group (BIG) 1-98 trial: an international, multicenter, randomized, double-blind, phase-III study comparing the aromatase inhibitor letrozole with tamoxifen in this clinical setting. Methods From 1998–2003, BIG 1-98 enrolled 8028 women to receive monotherapy with either tamoxifen or letrozole for 5 years, or sequential therapy of 2 years of one agent followed by 3 years of the other. Randomization to one of four treatment groups permitted two complementary analyses to be conducted several years apart. The first, reported in 2005, provided a head-to-head comparison of letrozole versus tamoxifen. Statistical power was increased by an enriched design, which included patients who were assigned sequential treatments until the time of the treatment switch. The second, reported in late 2008, used a conditional landmark approach to test the hypothesis that switching endocrine agents at approximately 2 years from randomization for patients who are disease-free is superior to continuing with the original agent. Results The 2005 analysis showed the superiority of letrozole compared with tamoxifen. The patients who were assigned tamoxifen alone were unblinded and offered the opportunity to switch to letrozole. Results from other trials increased the clinical relevance about whether or not to start treatment with letrozole or tamoxifen, and analysis plans were expanded to evaluate sequential versus single-agent strategies from randomization. Limitations Due to the unblinding of patients assigned tamoxifen alone, analysis of updated data will require ascertainment of the influence of selective crossover from tamoxifen to letrozole. Conclusions BIG 1-98 is an example of an enriched design, involving

    Identifying molecular markers for tumor recurrence is critical in successfully selecting patients with colon cancer who are more likely to benefit from adjuvant chemotherapy. We investigated the effect of single-nucleotide polymorphisms (SNP) within genes involved in oxaliplatin and fluoropyrimidines metabolism, DNA repair mechanisms, drug transport, or angiogenesis pathways on outcome for patients with stage II and III colon cancer treated with adjuvant chemotherapy. Genomic DNA was extracted from formalin-fixed paraffin-embedded samples of 202 patients with stage II and III colon cancer receiving oxaliplatin-based adjuvant chemotherapy from January 2004 to December 2009. Genotyping was performed for 67 SNPs in 32 genes using the MassARRAY (SEQUENOM) technology. Our results were validated in an independent cohort of 177 patients treated with the same chemotherapy regimens. The combination of the selectin E (SELE) rs3917412 G>A G/G and the methylentetrahydrofolate reductase (MTHFR) rs1801133 T/T genotypes was associated with a significantly increased risk for recurrence in both the training [RR = 4.103; 95% confidence interval (CI), 1.803-9.334; P = 0.001] and the validation cohorts (RR = 3.567; 95% CI, 1.253-10.151; P = 0.017) in the multiple regression analysis considering the stage, lymphovascular invasion, and bowel perforation as covariates. The combined analysis of these polymorphisms was also significantly associated with overall survival in both cohorts (RR = 3.388; 95% CI, 0.988-11.623; P = 0.052, and RR = 3.929; 95% CI, 1.144-13.485; P = 0.020, respectively). Our findings suggest that the SELE rs3917412 and MTHFR rs1801133 SNPs could serve as pharmacogenetic predictors of tumor recurrence in patients with early-stage colon cancer treated with oxaliplatin-based adjuvant chemotherapy, thus allowing personalized selection of treatment to optimize clinical outcomes.

    The Toll-like receptor (TLR) 7/8 agonist resiquimod has been used as an immune adjuvant in cancer vaccines. We evaluated the safety and immunogenicity of the cancer testis antigen NY-ESO-1 given in combination with Montanide (Seppic) with or without resiquimod in patients with high-risk melanoma. In part I of the study, patients received 100 μg of full-length NY-ESO-1 protein emulsified in 1.25 mL of Montanide (day 1) followed by topical application of 1,000 mg of 0.2% resiquimod gel on days 1 and 3 (cohort 1) versus days 1, 3, and 5 (cohort 2) of a 21-day cycle. In part II, patients were randomized to receive 100-μg NY-ESO-1 protein plus Montanide (day 1) followed by topical application of placebo gel [(arm A; n = 8) or 1,000 mg of 0.2% resiquimod gel (arm B; n = 12)] using the dosing regimen established in part I. The vaccine regimens were generally well tolerated. NY-ESO-1-specific humoral responses were induced or boosted in all patients, many of whom had high titer antibodies. In part II, 16 of 20 patients in both arms had NY-ESO-1-specific CD4⁺ T-cell responses. CD8⁺ T-cell responses were only seen in 3 of 12 patients in arm B. Patients with TLR7 SNP rs179008 had a greater likelihood of developing NY-ESO-1-specific CD8⁺ responses. In conclusion, NY-ESO-1 protein in combination with Montanide with or without topical resiquimod is safe and induces both antibody and CD4⁺ T-cell responses in the majority of patients; the small proportion of CD8⁺ T-cell responses suggests that the addition of topical resiquimod to Montanide is not sufficient to induce consistent NY-ESO-1-specific CD8⁺ T-cell responses.

    We report five cases of pattern alopecia in female patients who are undergoing hormonal anticancer therapy for the prevention of recurrence of breast cancer after surgery. Three patients demonstrated male pattern alopecia with receding frontal hairlines, and two patients demonstrated female pattern alopecia without receding hairlines. The detailed clinical history showed that the pattern alopecia of the patients developed after the full recovery of global hair loss of the entire scalp due to previous cytotoxic chemotherapy. All of the adjuvant hormonal anticancer drugs that were used in the patients are antiestrogenic agents, either aromatase inhibitors or selective estrogen receptor modulators. Considering androgen effect on the hair follicles of the fronto-parietal scalp, the androgen-estrogen imbalance caused by the drugs was thought to be the reason for the onset of pattern alopecia in the patients. In general, alopecia that develops during cytotoxic chemotherapy is well known to both physicians and patients; however, the diagnosis of pattern alopecia during hormonal anticancer therapy in breast cancer patients seems to be overlooked.

    Purpose: Long-term (LT) androgen suppression (AS) with radiation therapy (RT) is a standard treatment of high-risk, localized prostate cancer (PCa). Radiation Therapy Oncology Group 9902 was a randomized trial testing the hypothesis that adjuvant combination chemotherapy (CT) with paclitaxel, estramustine, and oral etoposide plus LT AS plus RT would improve overall survival (OS). Methods and Materials: Patients with high-risk PCa (prostate-specific antigen 20-100 ng/mL and Gleason score [GS] ≥7 or clinical stage ≥T2 and GS ≥8) were randomized to RT and AS (AS + RT) alone or with adjuvant CT (AS + RT + CT). CT was given as four 21-day cycles, delivered beginning 28 days after 70.2 Gy of RT. AS was given as luteinizing hormone-releasing hormone for 24 months, beginning 2 months before RT plus an oral antiandrogen for 4 months before and during RT. The study was designed based on a 6% improvement in OS from 79% to 85% at 5 years, with 90% power and a 2-sided alpha of 0.05. Results: A total of 397 patients (380 eligible) were randomized. The patients had high-risk PCa, 68% with GS 8 to 10 and 34% T3 to T4 tumors, and median prostate-specific antigen of 22.6 ng/mL. The median follow-up period was 9.2 years. The trial closed early because of excess thromboembolic toxicity in the CT arm. The 10-year results for all randomized patients revealed no significant difference between the AS + RT and AS + RT + CT arms in OS (65% vs 63%; P=.81), biochemical failure (58% vs 54%; P=.82), local progression (11% vs 7%; P=.09), distant metastases (16% vs 14%; P=.42), or disease-free survival (22% vs 26%; P=.61). Conclusions: NRG Oncology RTOG 9902 showed no significant differences in OS, biochemical failure, local progression, distant metastases, or disease-free survival with the addition of adjuvant CT to LT AS + RT. The trial results provide valuable data regarding the natural history of high-risk PCa treated with LT AS + RT and have implications for

    OBJECTIVE: This study was designed to evaluate prospectively survival after pancreaticoduodenectomy for pancreatic adenocarcinoma, comparing two different postoperative adjuvant chemoradiation protocol to those of no adjuvant therapy. SUMMARY BACKGROUND DATA: Based on limited data from the Gastrointestinal Tumor Study Group, adjuvant chemoradiation therapy has been recommended after pancreaticoduodenectomy for adenocarcinoma of the head, neck, or uncinate process of the pancrease. However, many patients continue to receive no such therapy. METHODS: From October 1991 through September 1995, all patients with resected, pathologically confirmed adenocarcinoma of the head, neck, or uncinate process of the pancreas were reviewed by a multidisciplinary group (surgery, radiation oncology, medical oncology, and pathology) and were offered three options for postoperative treatment after pancreaticoduodenectomy: 1) standard therapy: external beam radiation therapy to the pancreatic bed (4000-4500 cGy) given with two 3-day fluorouracil (5-FU) courses and followed by weekly bolus 5-FU (500 mg/m2 per day) for 4 months; 2) intensive therapy: external beam radiation therapy to the pancreatic bed (5040-5760 cGy) with prophylactic hepatic irradiation (2340-2700 cGy) given with and followed by infusional 5-FU (200 mg/m2 per day) plus leucovorin (5 mg/m2 per day) for 5 of 7 days for 4 months; or 3) no therapy: no postoperative radiation therapy or chemotherapy. RESULTS: Pancreaticoduodenectomy was performed in 174 patients, with 1 in-hospital death (0.6%). Ninety-nine patients elected standard therapy, 21 elected intensive therapy, and 53 patients declined therapy. The three groups were comparable with respect to race, gender, intraoperative blood loss, tumor differentiation, lymph node status, tumor diameter, and resection margin status. Univariate analyses indicated that tumor diameter < 3 cm, intraoperative blood loss < 700 mL, absence of intraoperative blood transfusions, and use

    Purpose: The excision repair cross-complementation 1 (ERCC1) enzyme plays a rate-limiting role in the nucleotide excision repair pathway and is associated with resistance to platinum-based chemotherapy in cancers of the head and neck and the lung. The purpose of this study was to evaluate the clinicopathologic and prognostic significance of ERCC1 expression in a cohort of early-stage breast cancer patients treated with breast conservation therapy. Methods and Materials: Paraffin specimens from 504 women with early-stage breast cancer treated with breast conservation therapy were constructed into tissue microarrays. The array was stained for estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) and ERCC1. This was then correlated with clinicopathologic factors and outcomes data. Results: ERCC-1 expression was evaluable in 366 cases (72%). In this group, 32% and 38% of patients received adjuvant chemotherapy and hormonal therapy, respectively. Increased ERCC-1 expression was found to be correlated with ER positivity (p < 0.005), lower T stage (p < 0.017), nodal negativity (p < 0.013), age >50 (p < 0.006), reduced use of adjuvant chemotherapy (p < 0.02), and increased use of adjuvant hormonal therapy (p < 0.004). ERCC1 expression did not correlate with locoregional recurrence-free survival, distant metastasis-free survival, cause-specific survival, or overall survival. In patients who were both ERCC1-negative and -positive, the use of chemotherapy predicted for worse distant metastasis-free survival (p = 0.05 and p = 0.07, respectively) but not cause-specific survival or overall survival. Conclusions: Although ERCC1 expression did not predict for outcome measures in this dataset, overexpression correlated with favorable prognostic factors such as ER positivity, lower T stage, nodal negativity, and age >50. To our knowledge, this is the first study investigating ERCC1 expression in patients receiving adjuvant radiation

    Radiotherapy has a not well-established role in the pre-operative and in the post-operative setting in gastric cancer (GC) patients. Randomized trials report controversial outcomes and impact on survival. In the D2 loco-regional node resection era, after a well-performed radical surgery, local treatment using radiotherapy combined to chemotherapy should be considered for locally advanced GC. Prognostic factors could help the better selection of subgroups that present high risk of loco-regional recurrence. Then, the addition of radiotherapy could improve the disease-free survival and also quality of life. There are no large prospective studies that have assessed specific factors predicting for recurrence or survival, but only retrospective series, some of them including high number of patients with homogeneous characteristics. In locally advanced GC adding radiotherapy to the post-operative chemotherapy seems to improve outcomes and quality of life. Prognostic factors such as T-stage, N-status, nodal ratio, and other histological factors should be considered to submit patients to post-operative combined treatment. Larger prospective series are necessary to investigate the role of combined chemoradiation after radical D2-resection, especially in locally advanced GC. Further prospective investigations are needed to suggest prognostic factors that have significant impact on survival and recurrence, improving the management and outcomes, particularly in locally advanced GC patients.

    Despite broad advances in molecularly targeted therapies, lung cancer remains the leading cause of cancer related mortality in the United States. Epidermal growth factor receptor (EGFR) mutations occur in approximately 17% of advanced non-small cell lung cancer (NSCLC) in the US population. The remarkable efficacy of small-molecule EGFR tyrosine kinase inhibitors (TKIs) in this unique subset of patients has revolutionized the therapeutic approach to lung cancer. The success of these agents in the metastatic setting leads to the logical question of what role these drugs may have in the adjuvant setting for patients with earlier stage disease. RADIANT, an international randomized, double-blind, placebo controlled phase III study in patients with completely resected stage IB to IIIA NSLC whose tumors expressed EGFR by IHC and EGFR amplification by FISH, attempted to answer the question of whether erlotinib would improve disease free survival and overall survival in the adjuvant setting. While RADIANT does not conclude for or against adjuvant use of EGFR-TKIs, all data points towards benefit in a selected population. As clinicians, we must continue to enroll to potentially practice changing therapeutic neoadjuvant and adjuvant chemotherapy studies internationally. PMID:27568486

Four NOACS: dabigatran, apixaban, rivaroxaban and edoxaban, have received regulatory approval in Europe from the European Medicines Agency. Numerous factors can influence the decision to prescribe a NOAC, the most important of which are assessment of stroke and bleeding risks. Given the variation in design of the pivotal phase III clinical trials investigating the efficacy and safety of NOACs, and in the absence of head-to-head comparative data, it is impossible to recommend one NOAC over the other. However, NOACS offer the opportunity for individualised therapy based on factors such as renal function, age or patient/doctor preference for once- or twice-daily dosing regimens. Dose reduction of some NOACS should be considered in at-risk patient populations. PMID:27617088

    Providing needed dental treatment, managing oral infection, and controlling pain are essential functions of dentists for helping patients maintain overall health during pregnancy. Medications commonly required for dental care consist of local anesthetics and associated vasoconstrictors, centrally and peripherally acting analgesics, sedative and anxiolytic agents, and antibiotics. Therapeutic drugs routinely used in dental practice are selected because of their known safety and effectiveness. However, for a pregnant patient requiring dental care, the agents routinely prescribed should be reevaluated for potential risks to the mother and/or fetus. The decision to administer a specific drug requires that the benefits outweigh the potential risks of the drug therapy. This article reviews and updates the recommendations for using dental therapeutic agents, thereby enabling general practitioners to select the safest drugs when treating pregnant dental patients.

    PubMed

    Sudoyo, Aru W

    2010-01-01

    Colorectal cancer (CRC) is a disease classified and based on genetic alteration resulting from interaction of environmental factors, individual cancer susceptibility and accumulated somatic changes of the colorectal epithelium. Advanced knowledge in genetics and epigenetics of colorectal cancer develops a hypothesis that various clinical manifestations of colorectal cancer are caused by different carcinogenesis pathways. Different carcinogenesis pathways and types of colorectal cancer appear to bring effects on different response against chemotherapy and prognosis. Chemotherapy is mainly provided for patients with stage III CRC which are also the largest proportion of CRC patients in Indonesia. However, it is also provided for some patients with high risk stage II CRC. Classically, clinical factors have been generally accepted as prognostic factors including depth of tumor invasion, regional nodal metastasis, vascular invasion, poor differentiation, and serologic tumor marker such as carcinoembryonic antigen (CEA). However, clinical and histopathological factors themselves do not provide accurate prediction for colorectal cancer prognosis and treatment. A biomolecular marker is necessary to provide such prediction. Numerous studies have been conducted to evaluate the molecular biological markers in order to determine either the possibility of successful treatment for colorectal cancer (predictive factor) or life-expectancy (prognostic factor). Results of several studies demonstrate different status of some molecular markers to determine successful treatment between stage II and stage III colorectal cancer. Certainly, such finding should be followed up but it shall be accepted that there will be a shift of paradigm of CRC treatment. Therefore, the success of colorectal cancer, excluding the patient's socioeconomic factors and the surgeon's skill, will depend extremely on molecular parameter and not only the stage.

    The occurrence of metastases severely affects prognosis for patients with cancer, making metastatic disease a daily societal challenge. Because of resistance to drugs, the potential curability with chemotherapy at the metastatic stage remains low. Large genomic analyses to identify new targets have their limitations due to intratumor heterogeneity when they are performed on tumor samples from primary tumors and because the functional value of molecular abnormalities in a cancer is usually not known. Additional tools are thus required for the development of new anticancer agents. The use of preclinical models is a key component of translational research in oncology. For four decades, xenograft models of human cancer cell lines injected subcutaneously in immunocompromised mice have been widely used, with disappointing results for predicting the clinical benefit of a new drug. Patient-derived xenografts are preclinical models rediscovered as innovative pharmacological tools, both for the preclinical development of anticancer drugs and as individual models for personalized treatment of metastatic disease. Here, we review the recent progress reported using patient-derived xenografts for the treatment of metastatic disease, and discuss the feasibility of their implementation in daily oncological care.

    Purpose: To evaluate outcomes of conservative surgery and radiation therapy (RT) treatment in patients with dermatofibrosarcoma protuberans. Methods and Materials: We retrospectively reviewed the medical records of 53 consecutive dermatofibrosarcoma protuberans patients treated with surgery and preoperative or postoperative radiation therapy between 1972 and 2010. Median tumor size was 4 cm (range, 1-25 cm). Seven patients (13%) were treated with preoperative RT (50-50.4 Gy) and 46 patients (87%) with postoperative RT (60-66 Gy). Of the 46 patients receiving postoperative radiation, 3 (7%) had gross disease, 14 (30%) positive margins, 26 (57%) negative margins, and 3 (7%) uncertain margin status. Radiation dose ranged from 50 to 66 Gy (median dose, 60 Gy). Results: At a median follow-up time of 6.5 years (range, 0.5 months-23.5 years), 2 patients (4%) had disease recurrence, and 3 patients (6%) had died. Actuarial overall survival was 98% at both 5 and 10 years. Local control was 98% and 93% at 5 and 10 years, respectively. Disease-free survival was 98% and 93% at 5 and 10 years, respectively. The presence of fibrosarcomatous change was not associated with increased risk of local or distant relapse (P=.43). One of the patients with a local recurrence had gross residual disease at the time of RT and despite RT to 65 Gy developed both an in-field recurrence and a nodal and distant recurrence 3 months after RT. The other patient with local recurrence was found to have in-field recurrence 10 years after initial treatment. Thirteen percent of patients had an RT complication at 5 and 10 years, and 9% had a moderate or severe complication at 5 and 10 years. Conclusions: Dermatofibrosarcoma protuberans is a radioresponsive disease with excellent local control after conservative surgery and radiation therapy. Adjuvant RT should be considered for patients with large or recurrent tumors or when attempts at wide surgical margins would result in significant morbidity.

    Endometrial cancer treatment ideally begins with a staging procedure including abdominopelvic washing, total abdominal hysterectomy, bilateral salpingo-oophorectomy, and lymph node evaluation. Recommendations for postoperative adjuvant radiotherapy are determined by recurrence risk. Patients who have undergone staging and have early stage I disease and an absence of high-risk features for recurrence generally are treated with surgery alone. Intermediate-risk patients--those with high-risk stage I disease and some stage II patients--may benefit from adjuvant radiation therapy. Several randomized trials show that radiation therapy improves locoregional control among intermediate-risk patients. The optimal type of radiation therapy, whether vaginal brachytherapy or whole-pelvic radiation therapy, remains undetermined, though treatment decision can be guided by risk factors not encompassed by the current staging system. Patients with high-risk stage II disease and stage III disease generally receive external-beam radiotherapy, often in combination with chemotherapy. Chemotherapy alone in advanced-stage patients is a consideration, given the results of the Gynecologic Oncology Group (GOG)-122 trial.

    Endometrial cancer treatment ideally begins with a staging procedure including abdominopelvic washing, total abdominal hysterectomy, bilateral salpingo-oophorectomy, and lymph node evaluation. Recommendations for postoperative adjuvant radiotherapy are determined by recurrence risk. Patients who have undergone staging and have early stage I disease and an absence of high-risk features for recurrence generally are treated with surgery alone. Intermediate-risk patients--those with high-risk stage I disease and some stage II patients--may benefit from adjuvant radiation therapy. Several randomized trials show that radiation therapy improves locoregional control among intermediate-risk patients. The optimal type of radiation therapy, whether vaginal brachytherapy or whole-pelvic radiation therapy, remains undetermined, though treatment decision can be guided by risk factors not encompassed by the current staging system. Patients with high-risk stage II disease and stage III disease generally receive external-beam radiotherapy, often in combination with chemotherapy. Chemotherapy alone in advanced-stage patients is a consideration, given the results of the Gynecologic Oncology Group (GOG)-122 trial. PMID:19476264

    Summary Background The Patient's Anastrozole Compliance to Therapy (PACT) program is a large randomized study designed to assess whether the provision of educational materials (EM) could improve compliance with aromatase inhibitor therapy in postmenopausal women with early, hormone receptor-positive breast cancer. Patients and Methods The PACT study presented a large, homogeneous dataset. The baseline analysis included patient demographics and initial treatments and patient perceptions about treatment and quality of life. Results Overall, 4,923 patients were enrolled at 109 German breast cancer centers/clinics in cooperation with 1,361 office-based gynecologists/oncologists. 4,844 women were randomized 1:1 to standard therapy (n = 2,402) or standard therapy plus EM (n = 2,442). Prior breast-conserving surgery and mastectomy had been received by 76% and 24% of the patients, respectively. Radiotherapy was scheduled for 85% of the patients, adjuvant chemotherapy for 38%. Reflecting the postmenopausal, hormone-sensitive nature of this population, only 285 patients (7%) had received neoadjuvant chemotherapy. Conclusions A comparison with epidemiological data from the West German Breast Center suggests that the patients in the PACT study are representative of a general postmenopausal early breast cancer population and that the findings may be applicable to ‘real-world’ Germany and beyond. Compliance data from PACT are eagerly anticipated. PMID:24419247

    We report on the efficacy and toxicity of a sequential high-dose therapy with peripheral blood stem cell (PBSC) support in 85 patients with high-risk stage II/III breast cancer. There were 71 patients with more than nine tumour-positive axillary lymph nodes. An induction therapy of two cycles of ifosfamide (total dose, 7.5 g m−2) and epirubicin (120 mg m−2) was given, and PBSC were harvested during G-CSF-supported leucocyte recovery following the second cycle. The PBSC-supported high-dose chemotherapy consisted of two cycles of ifosfamide (total dose, 12 000 mg m−2), carboplatin (900 mg m−2) and epirubicin (180 mg m−2). Patients were autografted with a median number of 3.7 × 106 CD34+ cells kg−1 (range, 1.9–26.5 × 106) resulting in haematological reconstitution within approximately 2 weeks following high-dose therapy. The toxicity was moderate in general, and there was no treatment-related toxic death. Twenty-one patients relapsed between 3 and 30 months following the last cycle of high-dose therapy (median, 11 months). The probability of disease-free and overall survival at 4 years were 60% and 83%, respectively. According to a multivariate analysis, patients with stage II disease had a significantly better probability of disease-free survival (74%) in comparison to patients with stage III disease (36%). The probability of disease-free survival was also significantly better for patients with oestrogen receptor-positive tumours (70%) compared to patients with receptor-negative ones (40%). Bone marrow samples collected from 52 patients after high-dose therapy were examined to evaluate the prognostic relevance of isolated tumour cells. The proportion of patients presenting with tumour cell-positive samples did not change in comparison to that observed before high-dose therapy (65% vs 71%), but a decrease in the incidence and concentration of tumour cells was observed over time after high-dose therapy. This finding was true for patients with relapse

    Between May 1975 and April 1981, 43 adult patients with high-grade soft tissue sarcomas of the extremities were prospectively randomized to receive either amputation at or above the joint proximal to the tumor, including all involved muscle groups, or to receive a limb-sparing resection plus adjuvant radiation therapy. The limb-sparing resection group received wide local excision followed by 5000 rads to the entire anatomic area at risk for local spread and 6000 to 7000 rads to the tumor bed. Both randomization groups received postoperative chemotherapy with doxorubicin (maximum cumulative dose 550 mg/m/sup 2/), cyclophosphamide, and high-dose methotrexate. Twenty-seven patients randomized to receive limb-sparing resection and radiotherapy, and 16 received amputation (randomization was 2:1). There were four local recurrences in the limb-sparing group and none in the amputation group (p/sub 1/ = 0.06 generalized Wilcoxon test). However, there were no differences in disease-free survival rates (83% and 88% at five years; p/sub 2/ = 0.99) between the limb-sparing group and the amputation treatment groups. Multivariate analysis indicated that the only correlate of local recurrence was the final margin of resection. Patients with positive margins of resection had a higher likelihood of local recurrence compared with those with negative margins (p/sub 1/ < 0.00001) even when postoperative radiotherapy was used. A simultaneous prospective randomized study of postoperative chemotherapy in 65 patients with high-grade soft-tissue sarcomas of the extremities revealed a marked advantage in patients receiving chemotherapy compared with those without chemotherapy in three-year continuous disease-free (92% vs. 60%; p/sub 1/ = 0.00008) and overall survival (95% vs. 74%; p/sub 1/ = 0.04).

    As a result of their previous experience with mitomycin C at high discontinuous doses in advanced gastric cancer, the authors studied its role as an adjuvant for locally advanced cases after surgical complete resection. Results from 70 evaluable patients are presented. Patients were allocated randomly to receive mitomycin C, 20 mg/m2 I.V. direct once every 6 weeks, four courses, or a placebo. After a follow-up period of 250 weeks, seven patients of treatment arm and 23 controls have already relapsed (p less than 0.001). Toxicity was moderate and controllable by symptomatic measures. The authors consider this investigation a positive contribution in the field of adjuvant therapy of gastric cancer. PMID:6407408

    Mirror neuron system(MNS) based therapy has been employed to treat stroke induced movement disorders. However, its potential effects on patients with hemispatial neglect were uninvestigated. The present study set out to test the therapeutic efficiency of video watching of series of hand actions/movements (protocol A) in two patients with left hemispatial neglect, due to the right hemisphere stroke. The video containing dynamic landscape of natural scene or cities but not human/animals was used as the protocol B. The “ABA” training procedure for 3 weeks therefore allows us to internally control the individual differences. Before and after each week of training, the Chinese behavioral inattention test- Hongkong version (CBIT-HK) was implemented to evaluate the hemispatial neglect severity. Functional magnetic resonance imaging (fMRI) experiment was implemented in two health subjects to reveal the difference of brain activation between protocol A and B. The results showed that protocol A rather than protocol B significantly improved the CBIT-HK scores at first and third weeks, respectively. Protocol A induced more bilateral activations including right inferior parietal lobe (supramarginal gyrus), which belongs to MNS and is also critical region resulting to hemineglect. Conclusion: MNS activation can provide a novel therapy for hemispatial neglect patients. PMID:25727354

    Purpose: Preclinical studies have shown that bevacizumab combined with radiotherapy (RT) induces a radiosensitizing effect. Published reports regarding the safety of combination therapy involving bevacizumab and RT are lacking. The purpose of this study was to analyze acute locoregional toxicity in patients with breast cancer receiving concurrent bevacizumab plus RT. Methods and Materials: After institutional review board approval was obtained, patients with breast cancer who received bevacizumab were identified; these patients were then cross-referenced with patients receiving RT. Toxicity was scored by the Common Terminology Criteria for Adverse Events. Patients were matched 1:1 with those who did not receive bevacizumab. Statistical analysis was performed to analyze toxicity between the two groups. Results: Fourteen patients were identified to have received bevacizumab plus RT. All patients receivedbevacizumab during RT without delay or treatment breaks; there were no RT treatment breaks in all patients. No patient receiving bevacizumab plus RT experienced {>=}Grade 3 toxicity; 3 matched control patients experienced a Grade 3 skin reaction. There was no difference in fatigue, radiation fibrosis, pneumonitis, or lymphedema between the two groups. Five patients (35%) developed reduction in ejection fraction; 2 with right-sided and 3 with left-sided treatment. Patients with left-sided treatment experienced a persistent reduction in ejection fraction compared with those receiving right-sided treatment. Conclusion: Concurrent bevacizumab and RT did not increase acute locoregional toxicity in comparison with matched control patients who did not receive RT alone. The addition of concurrent RT when treating the intact breast, chest wall, and associated nodal regions in breast cancer seems to be safe and well tolerated.

    Background: Neuraxial anesthesia greatly expands the anesthesiologist armamentarium, providing alternatives to general anesthesia, especially in the lower abdominal surgeries. Clonidine, an alpha-2 adrenergic agonist, has a variety of actions, including potentiation of effects of local anesthetics. This study was undertaken to assess the degree of sensory and motor block and postoperative analgesia provided by low dose (50 mcg) intrathecal clonidine admixed with bupivacaine. Aims: The aim of this study is to establish efficacy and safety of intrathecal clonidine as adjuvant to bupivacaine. Settings and Design: The type of the study was double-blind randomized trial. Materials and Methods: Hundred patients were randomly allocated in two groups, A and B. Group A received bupivacaine 0.5%, 3 ml with placebo (normal saline 0.33 ml) and Group B, bupivacaine 0.5%, 3 ml with clonidine 50 μg (0.33 ml). Statistical Analysis Used: Statistical Package for Social Sciences version 15.0 statistical analysis software. Results: Mean duration of motor block was significantly higher in Group B (280.80 ± 66.88 min) as compared with Group A (183.60 ± 77.06 min). Significant difference in duration of sensory block was noted between Group B (295.20 ± 81.17 min) and Group A (190.80 ± 86.94 min). Duration of postoperative analgesia was significantly higher in Group B as compared to Group A (551.06 ± 133.64 min and 254.80 ± 84.19 min respectively). Mean visual analog scale scores at different time intervals were significantly lower in the study group (except for 4-h time interval), but the control group had better hemodynamic stability as compared with study group. Conclusion: The findings in this study suggested that use of clonidine 50 μg added to bupivacaine for spinal anesthesia effectively increased the duration of sensory block, duration of motor block, and duration of analgesia.

    Purpose To examine the association of baseline body mass index (BMI) with the risk of recurrence or death in postmenopausal women with early-stage breast cancer receiving adjuvant tamoxifen or letrozole in the Breast International Group (BIG) 1-98 trial at 8.7 years of median follow-up. Patients and Methods This report analyzes 4,760 patients with breast cancer randomly assigned to 5 years of monotherapy with letrozole or tamoxifen in the BIG 1-98 trial with available information on BMI at randomization. Multivariable Cox modeling assessed the association of BMI with disease-free survival, overall survival (OS), breast cancer–free interval, and distant recurrence-free interval and tested for treatment-by-BMI interaction. Median follow-up was 8.7 years. Results Seventeen percent of patients have died. Obese patients (BMI ≥ 30 kg/m2) had slightly poorer OS (hazard ratio [HR] = 1.19; 95% CI, 0.99 to 1.44) than patients with normal BMI (< 25 kg/m2), whereas no trend in OS was observed in overweight (BMI 25 to < 30 kg/m2) versus normal-weight patients (HR = 1.02; 95% CI, 0.86 to 1.20). Treatment-by-BMI interactions were not statistically significant. The HRs for OS comparing obese versus normal BMI were HR = 1.22 (95% CI, 0.93 to 1.60) and HR = 1.18 (95% CI, 0.91 to 1.52) in the letrozole and tamoxifen groups, respectively. Conclusion There was no evidence that the benefit of letrozole over tamoxifen differed according to patients' BMI. PMID:23045588

    Tumor invasion and metastasis are complex biological processes. Matriptase and its endogenous inhibitor, hepatocyte growth factor activator inhibitor-1 (HAI-1) are involved in invasion and metastasis. To evaluate the ratio of matriptase/HAI-1 and their potential therapeutic value in ovarian cancer, HO-8910 human ovarian cancer cells and the homologous high-metastatic HO-8910PM cells were used as in vitro cellular models ovarian cancer. The invasive and metastatic abilities, and the expression of matriptase and HAI-1 in these cells were detected using scratch assays, Transwell chamber assays, reverse transcription-quantitative polymerase chain reaction, western blotting and fluorescent immunocytochemistry. Following infection with lentivirus-mediated matriptase-targeting small interfering RNA (siRNA), cell cycle progression and apoptosis were also analyzed. The migration distance and number of invading HO-8910PM cells were significantly increased compared with HO-8910 cells. HO-8910PM cells exhibited a significantly higher ratio of matriptase/HAI-1 mRNA levels compared with HO-8910 cells (0.51 vs. 0.24, ~2.2 fold increase). Compared with HO-8910 cells, the matriptase mRNA level was increased by ~3.6 fold in HO-8910PM cells, whereas the HAI-1 mRNA level was increased by ~1.7 fold. Similar increases in protein expression levels were also observed in HO-8910PM cells compared with HO-8910 cells. Migration and invasiveness were positively correlated with matriptase expression level (r=0.994, P<0.01) and the ratio of matriptase/HAI-1 (r=0.929, P<0.01). Downregulation of matriptase using siRNA resulted in inhibition of the invasive and metastatic abilities of HO-8910PM cells, cell cycle arrest in the G0/G1 phase and increased apoptosis. The present study demonstrated that ovarian cancer cell metastasis and invasion were more dependent on upregulation of matriptase levels than downregulation of HAI-1. Matriptase may be a potential adjuvant therapeutic target for inhibiting

    Purpose: To determine the rate of treatment deviations during combined modality therapy for rectal cancer in elderly patients aged 75 years and older. Methods and Materials: We reviewed the records of consecutively treated patients with rectal cancer aged 75 years and older treated with combined modality therapy at Massachusetts General Hospital and Brigham and Women's Hospital from 2002 to 2007. The primary endpoint was the rate of treatment deviation, defined as a treatment break, dose reduction, early discontinuation of therapy, or hospitalization during combined modality therapy. Patient comorbidity was rated using the validated Adult Comorbidity Evaluation 27 Test (ACE-27) comorbidity index. Fisher's exact test and the Mantel-Haenszel trend test were used to identify predictors of treatment tolerability. Results: Thirty-six eligible patients had a median age of 79.0 years (range, 75-87 years); 53% (19/36) had no or mild comorbidity and 47% (17/36) had moderate or severe comorbidity. In all, 58% of patients (21/36) were treated with preoperative chemoradiotherapy (CRT) and 33% (12/36) with postoperative CRT. Although 92% patients (33/36) completed the planned radiotherapy (RT) dose, 25% (9/36) required an RT-treatment break, 11% (4/36) were hospitalized, and 33% (12/36) had a dose reduction, break, or discontinuation of concurrent chemotherapy. In all, 39% of patients (14/36) completed {>=}4 months of adjuvant chemotherapy, and 17% (6/36) completed therapy without a treatment deviation. More patients with no to mild comorbidity completed treatment than did patients with moderate to severe comorbidity (21% vs. 12%, p = 0.66). The rate of deviation did not differ between patients who had preoperative or postoperative CRT (19% vs. 17%, p = 1.0). Conclusions: The majority of elderly patients with rectal cancer in this series required early termination of treatment, treatment interruptions, or dose reductions. These data suggest that further intensification of

    Pancreatic cancer is a devastating disease. It is the fourth leading cause of cancer-related death in Germany. The incidence in 2003/2004 was 16 cases per 100.000 inhabitants. Of all carcinomas, pancreatic cancer has the highest mortality rate, with one- and five-year survival rates of 25% and less than 5%, respectively, regardless of the stage at diagnosis. These low survival rates demonstrate the poor prognosis of this carcinoma. Previous therapeutic approaches including surgical resection combined with adjuvant therapy or palliative chemoradiation have not achieved satisfactory results with respect to overall survival. Therefore, it is necessary to evaluate new therapeutic approaches. Neoadjuvant therapy is an interesting therapeutic option for patients with pancreatic cancer. For selected patients with borderline or unresectable disease, neoadjuvant therapy offers the potential for tumor downstaging, increasing the probability of a margin-negative resection and decreasing the occurrence of lymph node metastasis. Currently, there is no universally accepted approach for treating patients with pancreatic cancer in the neoadjuvant setting. In this review, the most common neoadjuvant strategies will be described, compared and discussed. PMID:24212810

    We investigated gene expression profiles of the NF-κB pathway in patients with triple-negative breast cancer (TNBC) receiving adjuvant chemotherapy to determine the prognostic value of NF-κB pathway genes according to chemotherapeutic regimen. We used the nCounter expression assay to measure expression of 11 genes (NFKB1, NFKB2, RELA, RELB, REL, TP53, FOXC1, TBP, SP1, STAT3 and IRF1 genes) belonging to the NF-κB pathway using mRNA extracted from paraffin-embedded tumor tissues from 203 patients diagnosed with TNBC. Of the 203 patients, 116 were treated with a chemotherapeutic regimen containing doxorubicin. As revealed by the expression profiles of the 11 genes, increased expression of SP1 was associated with poor prognosis in TNBC patients treated with adjuvant doxorubicin chemotherapy (5-year distant recurrence-free survival [5Y DRFS], low vs. high expression [cut-off: median]: 92.3% vs. 71.6%, P = 0.001). In a multivariate Cox regression model, SP1 expression was a useful marker for predicting long-term prognosis in TNBC patients receiving doxorubicin treatment, and we thus suggest that SP1 expression could serve as a prognostic marker in these patients.

    A sandwich technique of adjuvant radiotherapy was used to treat twenty-three patients with rectal cancer. In this technique, low dose preoperative irradiation (500 rad in one treatment) was given to all patients followed by immediate surgery (usually an A-P resection); on the basis of histopathological findings, patients with stage B/sub 2/ and C rectal cancer were selectively given 4500 rad post-operative irradiation in 5 weeks. Nine patients had early lesions (stage A and B/sub 1/) and did not receive postoperative irradiation. Thirteen patients had stage B/sub 2/ and C disease and hence received the full course of postoperative irradiation. One patient was found to have liver metastasis at the time of surgery, and hence received only palliative therapy. Follow-up of these twenty-three patients ranges from 10 months to 24 months with a median follow-up of 15 months. Treatment was well-tolerated with few side effects. Only two of the twenty-two patients who were treated for cure have failed to date. Both patients had stage C/sub 2/ disease; one patient developed an anterior abdominal wall recurrence in the surgical scar 3 months post-treatment and the second patient developed brain and bone metastases. No patients have failed in the pelvis. We feel this technique of adjuvant therapy is a logical approach to the treatment of rectal cancer and has potential for improving survival. The rationale for this approach to adjuvant radiotherapy is discussed together with implications for survival.

    Background. This study evaluates the effect of adjuvant BEMER therapy in patients with knee arthrosis and chronic low back pain in a randomized double blind design. Methods. A total of 50 patients with chronic low back pain and 50 patients with osteoarthritis of knee took part in this study and were randomized into 4 groups. Hospitalized patients received a standardized physiotherapy package for 3 weeks followed by BEMER therapy or placebo. Results. In patients with low back pain, the comparison of the results obtained at the first and second visit showed a significant improvement in resting VAS scores and Fatigue Scale scores. The Oswestry scores and Quality of Life Scale scores showed no change. In patients with knee arthrosis, the comparison of the first and second measurements showed no significant improvement in the abovementioned parameters, while the comparison of the first and third scores revealed a significant improvement in the Fatigue Scale scores and in the vitality test on the Quality of Life Scale. Conclusions. Our study showed that BEMER physical vascular therapy reduced pain and fatigue in the short term in patients with chronic low back pain, while long-term therapy appears to be beneficial in patients with osteoarthritis of knee.

    2013-01-01

    Background Cancer-related fatigue (CRF) is one of the most common and distressing side effects of cancer and its treatment. During and after radiotherapy breast cancer patients often suffer from CRF which frequently impairs quality of life (QoL). Despite the high prevalence of CRF in breast cancer patients and the severe impact on the physical and emotional well-being, effective treatment methods are scarce. Physical activity for breast cancer patients has been reported to decrease fatigue, to improve emotional well-being and to increase physical strength. The pathophysiological and molecular mechanisms of CRF and the molecular-biologic changes induced by exercise, however, are poorly understood. In the BEST trial we aim to assess the effects of resistance training on fatigue, QoL and physical fitness as well as on molecular, immunological and inflammatory changes in breast cancer patients during adjuvant radiotherapy. Methods/design The BEST study is a prospective randomized, controlled intervention trial investigating the effects of a 12-week supervised progressive resistance training compared to a 12-week supervised muscle relaxation training in 160 patients with breast cancer undergoing adjuvant radiotherapy. To determine the effect of exercise itself beyond potential psychosocial group effects, patients in the control group perform a group-based progressive muscle relaxation training. Main inclusion criterion is histologically confirmed breast cancer stage I-III after lumpectomy or mastectomy with indication for adjuvant radiotherapy. Main exclusion criteria are acute infectious diseases, severe neurological, musculosceletal or cardiorespiratory disorders. The primary endpoint is cancer-related fatigue; secondary endpoints include immunological and inflammatory parameters analyzed in peripheral blood, saliva and urine. In addition, QoL, depression, physical performance and cognitive capacity will be assessed. Discussion The BEST study is the first randomized

    Chemotherapy-induced amenorrhea (CIA) is a side effect that occurs in patients with breast cancer (BC) as a result of chemotherapy. These patients require special treatments to avoid infertility and menopause. However, the factors controlling CIA, resumption of menstruation (RM), and persistence of menstruation after chemotherapy are unknown. The long-term prognosis for premenopausal patients with BC and the prognostic factors associated with CIA and RM are subject to debate. We performed a retrospective study by reviewing the medical records of 249 patients with BC (stage I to stage III) who were treated with cytotoxic chemotherapy. The median patient age was 43 (range, 26-55 years) and the median duration of follow-up was 64 months (range, 28-100 months). The medical records indicated that 219 patients (88.0%) scored as positive for the hormone receptor (HR); the majority of these patients completed chemotherapy and then received additional therapy of tamoxifen. Our analyses revealed that 88.0% (n = 219) of patients experienced CIA, and the percentage of RM during follow-up was 48.6% (n = 121). A total of 30 patients (12.0%) did not experience CIA. Disease-free survival (DFS) was affected by several factors, including tumour size ≥2 cm, node positivity, HR negative status, and body mass index ≥23 kg/m. Multivariate analysis indicated that tumour size ≥2 cm remained as a significant factor for DFS (hazard ratio = 3.3, P = 0.034). In summary, this study finds that the majority of premenopausal patients with BC (stage I to stage III) who receive chemotherapy experience CIA and subsequent RM. Although tumour size ≥2 cm is negatively associated with DFS, RM after CIA is not associated with poor prognosis.

    The evaluation and treatment of erectile dysfunction (ED) differs from that of many medical conditions. An intimate dialogue between the patient and physician must be established for accurate assessment of ED severity and successful therapy. Patient and partner education on the nuances of oral phosphodiesterase inhibitor therapy is important to maximize treatment success with this currently first-line therapy. Realistic expectations for the erectile response and patience are necessary to resume satisfactory sexual functioning. Relationship issues or partner resistance can contribute to a suboptimal erectile response to therapy, in which case the patient may benefit from sexual therapy referral. PMID:16985980

    Within the integrative medicine one of the most frequently used adjuvant cancer biotherapies is based on aqueous mistletoe (Viscum album) extracts. Tumor growth inhibition, stimulation of host immune response and improvement of the quality of life are the positive effects of mistletoe therapy described in several preclinical and clinical studies. However, cumulative results of the evidence based medicine findings on such treatments are rarely given. Therefore, this paper evaluates the evidence based findings describing effects of the Viscum album extract Isorel in cancer therapy with respect to the type of therapy, stage and type of illness. This study presents cumulated data for 74 patients with different types and stages of cancer treated by Viscum album extract as adjuvant treatment to different conventional therapies, mostly combined surgery and radiotherapy. The biotherapy effectiveness was evaluated according to the outcome as (1) no major therapeutic improvement (15% of patients), (2) prevention of tumor recurrence (47% of patients) and (3) regression of cancer (38% of patients). Notably, there was no obvious health worsening during the follow up period at all. Thus, the results obtained for conventional anticancer therapies combined with adjuvant biotherapy based on Viscum album extract seem to be beneficial for the majority of cancer patients (85%) without serious side effects.

    Abstract According to the National Comprehensive Cancer Network (NCCN) guidelines, treatment plans for nonsmall cell lung cancer are to be based on cancer stage. Cancer staging for patients with resectable disease has been based on pathologic stage instead of preoperative clinical stage. However, the possibility of occult mediastinal lymph node metastases could lead to discrepancy between clinical and pathologic stage. While multi-modality treatments may be beneficial for patients with locally advanced disease, most studies have been based on clinical stage. The aim of this study was to identify the beneficial impact of neoadjuvant therapy and the prognostic value of final pathologic stage in these patients. This study enrolled 530 lung cancer patients who received anatomic resection and mediastinal lymph node dissection at Chang Gung Memorial Hospital from January 2005 through June 2011. All resected specimens were examined by pathologists. Postoperative adjuvant therapies were given according to NCCN guideline recommendations. The clinico-pathologic factors of these patients were collected and analyzed. Patients not receiving neoadjuvant therapy had a better probability of disease-free survival (P < 0.001) and overall survival (P = 0.0005), as well as a lower incidence of early relapse. Patients not receiving neoadjuvant therapy had a better disease-free survival rate in stages IA (P < 0.001), IB (P = 0.002), and IIB (P = 0.0117) from the point of view of final pathologic stage. Patients receiving neoadjuvant therapy may experience a higher incidence of early relapse. Neoadjuvant therapy did not show definite benefits in the disease-free and overall survival rates from the point of view of final pathologic stage. Pathologic stage of nonsmall cell lung cancer patients who presented with resectable disease after neoadjuvant therapy did not predict the prognosis. PMID:26448022

    The actuality is in quite a high proportion of the dermatoses structure. Unclear etiological factors and pathogenesis, the polymorphism of clinical progression, torpid to traditional methods and therapy agents are often observed. The aim of the research is the development of a differentiated treatment of the patients with urticaria, taking into account the functional state of the thyroid gland and its participation in the formation. of autoimmune processes. 127 patients with chronic idiopathic urticarial aged 15-67 were observed (49 of them were men and 78--women). 20 healthy individuals formed the control group. The levels of thyroxine, thyroid peroxidise and thyroglobulin in the blood serum were determined. Dysfunctional state of the thyroid gland and its association with autoimmune processes were specified. The results obtained allowed to justify, develop and implement into the clinical practice the differentiated (depending upon the severity of dermatosis) treatment of the patients with urticaria using the narrow spectroscopic photo and balneo acupuncture which allows to limit the pathologic process.

    Background. The impact of drug prescriptions in real life as opposed to strict clinical trial prescription is only rarely assessed, although it is well recognized that incorrect use may harm patients and may have a significant impact on health care resources. We investigated the use and effectiveness of adjuvant trastuzumab in daily practice compared with the effectiveness in clinical trials. Methods. We included all patients with stage I–III invasive breast cancer, irrespective of human epidermal growth factor receptor 2 (HER2) status, diagnosed in five hospitals in the southeast of The Netherlands in 2005–2007. We aimed to assess the actual use of adjuvant trastuzumab in early HER2-positive breast and its efficacy in daily practice. Results. Of 2,684 patients included, 476 (17.7%) had a HER2-positive tumor. Of these, 251 (52.7%) patients had an indication for trastuzumab treatment of which 196 (78.1%) patients actually received it. Of the 225 patients without an indication, 34 (15.1%) received trastuzumab. Five-year disease-free survival was 80.7% for (n = 230) patients treated with versus 68.2% for (n = 246) patients not treated with trastuzumab (p = .0023), and 5-year overall survival rates were 90.7% and 77.4%, respectively (p = .0002). The hazard ratio for disease recurrence was 0.63 (95% confidence interval, 0.37–1.06) for trastuzumab when adjusting for potential confounders. Conclusion. This study shows that in real life, patients treated with trastuzumab in early-stage HER2-positive breast cancer had a 5-year disease-free and overall survival comparable to prior randomized trials. For informative decision making, real-life data are of additional value, providing insight on outcome of patients considered ineligible for treatment. PMID:26099745
